An Indonesian student described as Britain's most prolific rapist has been jailed for at least 30 years for 159 offences against 48 men.
Reynhard Sinaga filmed himself with young, drunk men after inviting them to his home in central Manchester and spiking their drinks.
Videos of dozens more victims were found, but police haven't been able to identify them all.
Prosecutor Ian Rushton says some victims didn't even know they'd been attacked as they were drugged after drinking.
