Officers are appealing for assistance to find three men who robbed an autistic man in November.

The three men, pictured below, were all involved in the offence which took place on board the number 74 bus between Dudley and GreatBridge on Saturday 12 November 2016 at around 4.15pm.

The 22-year-old victim boarded the bus in Castle Street, Dudley, and went to sit upstairs where 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. He managed to leave the bus outside Pure Gym in Dudley Port.

Anyone who recognises the men in the CCTV images, or who witnessed the attack, is asked to contact PC Drew Turner on 101, using extension 851 3126.
