Charged: Rejean Hermel Perron (pictured) has been accused of holding a woman captive for five days and subjecting her to multiple sexual assaults . A dog walker used nail clippers to free a kidnapped woman who police say was held prisoner and sexually assaulted by a Canadian man for five days. The 27-year-old sex trade worker emerged from a home in Toronto, Canada, bound by handcuffs, badly bruised and naked from the waist down begging for help. Peter Hamilton heard her cries as he was passing by and desperately tried to free her from her restraints. She told him that her kidnapper was still inside, but had fallen asleep. Mr Hamilton wanted to call the police, but had left his cell phone at home, forcing him to take out the only item he had on him - the nail clippers. Police claim Rejean Hermel Perron held the alleged victim at gunpoint on March 31 when she refused to go inside. He is then said to have held the woman for five days, subjecting her to sexual assaults including 'ritualistic actions' that officers said they were 'unfamiliar with'. Detectives believe there could be more victims who have yet to come forward. The 43-year-old is alleged to have met the woman, in the Sherbourne and Shuter Street area of the city before the pair returned to his home. The National Post reports that she became 'uncomfortable' and made it clear she wanted to leave. But he then allegedly produced the weapon and restrained her with duct tape and handcuffs. Police say she was subjected to multiple sexual assaults. Perron was arrested on Monday and later charged with sexual assault with a weapon, kidnapping, forcible confinement and assault. Describing the dramatic escape, Mr Hamilton told the CBC how he was walking his dog in the Dundas Street East and Jones Street area when he heard desperate pleas for help. Hero: Dog walker Peter Hamilton heard the woman's cries for help before he saw her come out of the house bound by restraints and naked from the waist down . Quick thinking: He wanted to call the police but left his cell phone at home, so had to use the only implement he had on him to free the woman - his nail clippers . He said a woman appeared on a veranda of a home but could not move further because of the restraints on her hands and feet. She warned him her kidnapper was still armed and inside the home. Mr Hamilton told CBC: 'My first thought was 'how do I get her out of here?' 'I knew this was a dangerous situation. I couldn't leave her, but I could not go back to my house to get my phone.' When a man emerged from the home, Mr Hamilton stood up ready for a confrontation. But the man then turned and fled, it is reported. Mr Hamilton added: 'This is where it could have taken a turn for the worse,' said Hamilton. 'He came out and he ran. He saw us and he just ran and that was a very good thing.' 'She was very emotionally distressed and she said, "I'm sorry I have to put you through this." There was nothing to apologize for. 'It's just the right thing to do. We live in a society where sometimes people turn a blind eye to what's going on around them.' In part, he has thankful for having his dog, as he wouldn't have been walking through the neighborhood for any reason. He told the Toronto Star: Without having that dog, I wouldn't have taken a walk through the neighbourhood, and if he hadn't taken a walk, he wouldn't have encountered a shocking crime in progress, and wouldn't have had the opportunity to intervene and possibly save a woman's life. 'Whatever fate or destiny comes into it, the dog has as much of a part. 'The horror of what happened to her, of what she had gone through, hadn't really sunk into me yet. 'What sinks into you is the horror you're seeing right now, which is that there's a naked woman on the floor in handcuffs who needs help.' After he contacted police, Mr Hamilton said he spent the day with his wife and went for a hike out of town. 'That was good. It calmed everybody down,' he said. The woman was rushed to hospital after passers-by called emergency services and is said to be recovering. Crime scene: After Mr Hamilton helped free the woman, a man emerged from the house, so they ran. The alleged victim is now being treated in hospital .
