THREE thugs robbed an autistic man at knifepoint aboard a Black Country bus.

The 22-year-old victim had boarded the number 74 bus in Castle Street, just outside Dudley Zoo, at around 4.15pm on November 12 last year.

When he went to sit upstairs, he was approached by the men and assaulted - they made off with his cap and tried to steal his phone.

The victim was threatened with a knife as he tried to get away and was followed downstairs to the lower deck. but managed to leave the bus outside Pure Gym, Dudley Port.

Police have released CCTV of the suspects and are urging anyone who recognises them or witnessed the attack to call PC Drew Turner on 101, using extension number 851 3126.
