A Calgary court was shown graphic video Thursday that was recorded by a man who says he was sexually assaulted by former forensic psychiatrist Aubrey Levin.

Levin is accused of sexually assaulting 10 male patients.

The court was shown two videos that were secretly recorded by one of his patients who claims to have been sexually assaulted.

The man, identified as R.B. in court, was on probation at the time the videos were taken and had been ordered by a court to see Levin twice a month.

The man said he had told authorities about previous assaults and no one believed him, so he bought a spy watch and brought it to his appointments.

Both videos show Levin undoing the man’s belt and jeans and fondling the man. In the second video, the psychiatrist had both hands on the man's genitalia for about 10 to 15 minutes.

Earlier Thursday, court heard from the man’s lawyer, who turned the tapes over to police after viewing them.

After Levin was arrested, nearly two dozen other former patients came forward with abuse allegations.
