Granada Reynhard Sinaga

Greater Manchester Police are now trying to trace another 60 men who they believe were victims of Sinaga, who drugged men and filmed himself violating them.

The Attorney General's Office referred the 30-year minimum jail terms handed to McCann and Sinaga to the Court of Appeal as "unduly lenient" earlier this year.

Greater Manchester Police believe that Reynhard Sinaga committed sexual offences against 206 men in Manchester, with 60 still not identified.
