A teenager was forced to have oral sex with three men at the Kajang Prison, Harian Metro reported.
The 18-year-old from Sungei Petani, Kedah, claimed that one of the men even tried to sodomise him.
The teen was taking part in a marching event organised by the prison when he was pulled by the three men into a corner and forced to have oral sex with them.
According to district police chief Asst Comm Ab Rashid Ab Wahab, the teen was not able to fight back and was forced to do as he was told.
"Immediately after the incident, the victim reported it to one of the wardens before a police report was made," he said.
The victim was brought to the Kajang hospital for a check-up and doctors confirmed that no object had been forced into the victim's anus.
"The men have been detained. They were told to attend an identification parade after we found traces of semen belonging to the three men," said ACP Ab Rashid.
"We are now waiting for the court to tell us the next course of action."
