Police seek man who forced boys into sex act

Two boys were forced to fight each other, steal, and perform a sex act by a man who claimed to be carrying a knife.

The teenagers were on the top deck of a bus in Brixton, London, on February 11 when the suspect got on and approached them.

He threatened them and forced them off the 133 bus in the Elephant and Castle area before making them fight each other in a park and steal from a nearby shop.
