 NEW YORK (AP) — A doctor who appears to have been the target of a former physician who started shooting at a hospital, killing one person and injuring six, said he has no idea why he would have been singled out. 
 
 Dr. Kamran Ahmed told the New York Post he wasn't the only one Dr. Henry Bello had a problem with. 
 
 However, "he never argued with me," Ahmed said. "I don't know why he put my name." 
 
 A law enforcement official told The Associated Press that Bello arrived at Bronx Lebanon Hospital in the Bronx on Friday with an assault rifle, which was bought in upstate New York about a week earlier, hidden under his lab coat and asked for a doctor he blamed for his having to resign, but the doctor wasn't there at the time. The law enforcement official wasn't authorized to discuss an ongoing investigation and spoke on the condition of anonymity. 
 
 Ahmed, who specializes in the early detection and treatment of dementia, said Bello "had a problem with almost everybody, so I'm not the only one. That's why they fired him, because so many people complained." 
 
 Authorities said Bello went to the 16th and 17th floors and started shooting anyway, killing Dr. Tracy Sin-Yee Tam, who, like him, was a family medicine doctor. Hospital officials said that Tam normally worked in one of the hospital's satellite clinics and was covering a shift in the main hospital as a favor to someone else. 
 
 "It makes you think that anything can happen to anybody," said Tam's neighbor Alena Khaim, who saw Tam's sister outside the home Friday night overcome with grief, shaking and unable to walk. "She was such a sweet girl. You would never think something like that would happen, but it happened." 
 
 Before the shooting, Bello sent an email to the Daily News, blaming colleagues he said forced him to resign two years earlier. 
 
 "This hospital terminated my road to a licensure to practice medicine," the email said. "First, I was told it was because I always kept to myself. Then it was because of an altercation with a nurse." 
 
 Bello's former co-workers described a man who was aggressive, loud and threatening. Bello had warned his former colleagues when he was forced out in 2015 that he would return someday to kill them. 
 
 "All the time he was a problem," said Dr. David Lazala, who trained Bello. 
 
 When Bello was forced out in 2015, he sent Lazala an email blaming him for the dismissal. 
 
 Bello died from a self-inflicted gunshot. The six injured people were hospitalized. 
 
 Detectives searched the Bronx home where Bello was most recently living and found the box where the gun came from. They later determined it was bought at a gun shop in Schenectady on June 20.

 This story has been corrected to show Bello had an assault rifle, not an automatic weapon. ||||| The doctor who dodged death at Bronx-Lebanon Hospital in the Bronx — at the hands of an assault weapon-toting, crazed former colleague — was shocked to be singled out by the killer. 
 
 “I was surprised,” Kamran Ahmed told The Post. “Why me?” 
 
 Ahmed, 48, said he had worked with shooter Henry Bello, 45, but that he wasn’t the only one Bello had a problem with. 
 
 “He started working there a couple of months after I was hired,” Ahmed said at his Bath Beach apartment Saturday night. 
 
 “He is not only after me, he is after a lot of people. He had a problem with almost everybody, so I’m not the only one. That’s why they fired him, because so many people complained. 
 
 “The strange thing was that he was nice with me,” added Ahmed, who specializes in the early detection and treatment of dementia. 
 
 “He never argued with me. I don’t know why he put my name.” 
 
 Bello was forced to resign from Bronx-Lebanon Hospital in 2015 amid a sexual harassment scandal. 
 
 He had vowed to return to the facility to kill Ahmed — even leaving a series of email, text and phone threats — and tried to make good Friday on his chilling pledge. 
 
 By luck, Ahmed was not working Friday. 
 
 Instead, Bello, dressed in a white medical coat to conceal an AM-15 rifle, spotted Dr. Roger Green on the 16th floor. 
 
 “Why didn’t you help me out when I was in trouble?” Bello demanded of Green as he pulled his AM-15 assault rifle from its hiding spot and took aim. 
 
 “Gun! Gun! Gun!” Green yelled as he fled, raising the first warnings of an active shooter inside the hospital. 
 
 Bello then made his way to the 17th floor, where he randomly killed Dr. Tracy Tam , 32, briefly set fire to the nurse’s station and eventually committed suicide. Along the way, he murdered Tam and shot six others. 
 
 Ahmed, a resident in family medicine and a father of three, claimed he only talked professionally with Bello while the two worked together. 
 
 “I didn’t see him since he got fired. He was fine with me, but he had many arguments,” he said. 
 
 He praised Tam as “excellent. Everybody loved her. She loved to teach us. I feel so sorry about her. She was there to cover one of the attending. She was in outpatient usually. Unfortunately she was the victim.” 
 
 A day after the rampage, Ahmed went to a staff meeting with a hospital official, he said. 
 
 “Everybody was there and we prayed [and] hugged each other to support each other.” 
 
 He plans to see Bello’s other victims tomorrow. 
 
 “I heard they are getting better. But one is still critically ill,” Ahmed noted.
