A man is accused of holding his girlfriend captive for days and forcing her to perform a sex act on his dog while he filmed.
Between June 28 and July 4, Justin Mustafa, 24, also allegedly beat and choked the woman and forcibly injected her with heroin multiple times.
On July 5, the woman showed up at the Falmouth police station and told police it was the first time since the 28th she had been able to get away from Mustafa.
She also told investigators that, when he forced her to perform the sex act on the dog, he filmed the incident and told her he would show other people the recording if she told anyone about what he had done.
Mustafa was arrested July 6. He has now pleaded not guilty to a slew of charges including assault, battery, bestiality, and malicious destruction of property.
Investigators say the victim told them the abuse started because Mustafa believed she had been unfaithful to him while he was in jail.
Mustafa had spent a year in jail that began in February 2012, after he pleaded guilty to filming a sexual encounter with a woman without her consent. He hid the camera in the closet while the two had sex, then later sent a copy to the victim and her new boyfriend.
