A GANG of 40 youths is terrorising city streets on weekends with robbery and bashing sprees.
The gang, whose members are as young as 12, has committed at least 50 crimes in the past three months.
The gang recently bashed a young Jehovah's Witness with his own skateboard in the Alexandra Gardens before tossing the board into the Yarra.
Senior police fear the gang may seriously injure or inadvertently kill someone if not stopped soon ...
Police say the gang is made up almost exclusively of Polynesian youths who have devised a series of initiation rituals that potential members must pass before they can join.
