London – A graduate student from Indonesia living in Manchester, England, was sentenced Monday to life in prison for raping or sexually assaulting 48 men.

Reynhard Sinaga, 36, met his inebriated victims outside of nightclubs and lured them back to his apartment, where he drugged and attacked them, filming the assaults on his cellphones.

A crown prosecutor called him the “most prolific rapist in British legal history.”
