An investigation has concluded Freddie Gray broke his neck after falling head-first into the back of the police van as it was moving, it was reported today. Medical and law enforcement sources briefed on the police investigation told ABC News Gray's 'catastrophic' head injuries were consistent with hitting a bolt 'in the back door of the van'. They claimed there was 'no evidence' Gray sustained a fatal spine injury during his arrest, which was caught on camera on a street side on April 12. According to ABC's sources, Gray was standing in the van, bent over with his hand cuffed behind his back and his head pointing towards the back door. It is believed he fell into the door, breaking his neck. SCROLL DOWN FOR VIDEO . A report claims Freddie Gray broke his neck when he fell head-first into the back of the van as it was moving .

It was picked up by a privately-owned security camera . According to the latest police press conference, these are the stops the van made transporting Freddie Gray . The news comes hours after Baltimore Police admitted the van transporting Gray made a previously unreported stop. The mysterious detail was picked up by a privately-owned security camera, and will be integral to the police investigation into Gray's death, which was completed and handed to the state prosecutor on Thursday morning. It is not known why the van stopped at the corner of North Fremont Ave and Mosher Street before it made another two stops then finally transported Gray to the hospital. And police have yet to clarify why Gray would have been standing without a seat belt on. Just nine days before his arrest, the Baltimore Police Department issued a new policy, making it obligatory to belt all inmates placed in the back of a transport van. Revelation: Police Commissioner Anthony Batts revealed a private security camera captured the van making an unknown stop. He refused to elaborate on the details of the new information . Police Commissioner Anthony Batts refused to elaborate on the new information. He said the contents of the report, which was completed and handed to the State Attorney at 8.50am Thursday, will remain confidential as they continue to investigate. Six officers have been suspended with pay over the incident, and the department has admitted Gray - who was asthmatic - should have been given the medical help he requested. The report that Gray fell inside the van corroborates claims he was given a 'rough ride' by the van driver, who is the only officer yet to deliver a statement to the investigators, according to ABC. The van in which Gray was injured is a Chevrolet Express - the same model of vehicle which has been modified into the 'Scooby' van driven by Hillary Clinton. As the police department, Mayor's office, and state prosecutors refuse to address the development, it has done nothing but fuel anger and speculation surrounding the circumstances of Gray's arrest more than two weeks ago. A relative of one of the suspended police officers told CNN she believes Gray was injured during his arrest outside the van. Her family member, she said, was based inside the van, and she fears he will be made a scapegoat for something he 'didn't do'. However, this theory is at odds with the medical examiner's report which allegedly found Gray sustained injuries by falling over inside the van, where he had been placed without a seat belt. The woman, who spoke on the condition of anonymity, told CNN her family member was in the van with Gray as he screamed and cried for medical help. But she believes the spinal injury which led to Gray's death was inflicted earlier, during his arrest on April 12. In an appeal that echoes Gray's family, she is calling for the police department to conduct a thorough investigation that will determine which of the six suspended police officers dealt the fatal blow. 'Six officers did not injure this man,' she told Don Lemon. Secret stop: This is the corner where the police van was spotted making a previously unreported stop . These are the security cameras outside a grocery which picked up the secret stop . Jung Hwang's convenience store's camera footage revealed a new stop the police van made while transporting Freddie Gray . 'Six officers didn't put him in the hospital. 'I'm worried that instead of them figuring out who did, that six officers are going to be punished behind something that maybe one or two or even three officers may have done to Freddie Gray.' Her words came after a police document was leaked to the Washington Post, in which the other prisoner in the transport van with Gray said he could hear the 25-year-old slamming himself against the wall. The prisoner speculated that Gray was trying to hurt himself. In the documents, the unidentified prisoner says he was loaded into a police van after Gray on April 12, and apparently told investigators that he heard Gray 'banging against the walls' and 'intentionally trying to injure himself'. However, he admits he could not see what Gray was doing, since they were separated by a metal partition. The statement was cited in a warrant to search an arresting officer's clothing for possible traces of Gray's DNA. The van in which Gray was injured is a Chevrolet Express - the same model of vehicle which has been modified into the 'Scooby' van driven by Hillary Clinton . The assertion that Gray may have caused his own death in the back of the police van was quickly rejected by an attorney hired by his family. 'We disagree with any implication that Freddie Gray severed his own spinal cord,' attorney Jason Downs told the Post. 'We question the accuracy of the police reports we've seen thus far, including the police report that says Mr Gray was arrested without force or incident.' Outrage over the unexplained death of a black man in Baltimore, Maryland prompted nationwide protests against police brutality on Wednesday from Houston to Boston. Baltimore has been the scene of near-nightly protests ever since the April 19 death of 25-year-old Freddie Gray, who is believed to have been fatally injured while in police custody. State Attorney Marilyn Mosby urged the public to be patient as she reviews the information. 'While we have and will continue to leverage the information received by the department, we are not relying solely on their findings but rather the facts that we have gathered and verified,' Mosby said on Thursday. 'We ask for the public to remain patient and peaceful and to trust the process of the justice system.' Freddie Gray: The 25-year-old was poisoned by lead paint as a child growing up in Baltimore . Freddie Gray was a 25-year-old African-American who grew up in Baltimore's impoverished west side . Nicknamed 'Pepper', he was described by an ex-girlfriend as happy-go-lucky with an infectious sense of humor. The Baltimore police knew him, however, as a 5ft-8ins felon who had notched up at least 18 arrests and a handful of convictions - mainly for Class A drugs but also burglary, assault and illegal gambling. He was said to have set off running at the sight of police patrolling a well known open-air drug market. He was taken into custody for possession of a switchblade and during transport to the station he experienced what officers described as 'a medical emergency'. Gray, who had asthma, requested an inhaler and had trouble breathing in the van, but police didn't provide his inhaler. According to Gray's family his spine was severed 80 per cent at his neck, three vertebrae were fractured and his larynx was injured. Court papers describe Gray's childhood as problematic. He lived with his heroin-addicted disabled mother in a home in Sandtown-Winchester that contained enough poisonous lead in the peeling painted walls and windowsills for a court settlement to conclude that he and his two sisters were incapable of leading normal functioning lives. Lab tests conducted in the 1990s showed that they had levels of lead in their blood nearly double what the state of Maryland defines as the minimum for lead poisoning. In Baltimore, more than 2,600 children have been found to have high levels of lead in their blood, according an annual report released by the Maryland Department of the Environment in 2014. 'This is the toxic legacy of lead-based paint,” Ruth Ann Norton, head of the Green & Healthy Homes Initiative and a founding member of the Maryland Lead Poisoning Prevention Commission, told the Baltimore Sun. 'Our kids are ill equipped to stay in the classroom, finish school. They’re very unlikely to go on to higher education. They’re less likely to be able to hold a job', she said. 'They’re less equipped to be able to overcome the poverty and other circumstances that pull them down. Children with lead poisoning will have defects, regardless of whether their parents are ‘nice’ or not.' Gray lived off the resulting 'lead check' settlement although it is unclear exactly how much he received. Whatever money he did have he was said to spend buying designer accessories. The Sandtown neighborhood is a 72-block neighborhood made up of almost entirely of African Americans. More than one-third of residents live below the poverty line, and nearly a quarter are unemployed. The majority of Maryland's state prison population are said to said to hail from Sandtown, according to the Justice Policy Institute.
