( CNN ) -- A Connecticut paramedic has been charged in the alleged sexual assault last month of a woman who was only semiconscious in the back of an ambulance , according to police . Mark Powell , 49 , was charged with first-degree sexual assault and unlawful restraint after he turned himself over to authorities Thursday , according to Hamden Police Capt . Ronald Smith . Smith said the 22-year-old woman received emergency medical treatment after hitting her head on Christmas Day and was transported to Yale-New Haven Hospital . It was during that time in the ambulance that the alleged victim , who was strapped to a stretcher , was assaulted , Smith said , citing the woman 's account . The woman said she waited three days to report the incident because she was embarrassed and afraid , according to Smith . The American Medical Response released a statement earlier this week saying that Powell has been placed on administrative leave . `` AMR takes very seriously our responsibility to provide safe care and transport for our patients , and we do not tolerate any kind of abusive behavior , '' said Charles Babson , General Manager of American Medical Response . Powell has been released on $ 25,000 bond and is scheduled to appear in court January 19 . It is unclear whether he has retained legal counsel .
