Muggers threatened to knife a student before punching him and stealing his wallet.

The 22-year-old had just left Wembley Central station when he was attacked at 10pm on Friday.

A group of three youths approached and one asked for a cigarette which he handed over. They then demanded cash, saying: ñIf I find any money on you IÍll knife you.î

The victim tried to walk away but he was punched in the face and stomach and pushed into a corner where his wallet containing £50 cash was stolen.
