A man exposed himself to an 11-year-old girl onboard a bus.

The victim was travelling on the upper deck of the 149 bus, along Kingsland Road in Hackney, when she noticed a man sitting near to her on January 26 this year.

Police said at around 3.50pm, the man began to change seats a number of times to move nearer to the girl.

Once he was on the same row, he exposed himself to the girl before getting off the bus.

Metropolitan Police have now released a CCTV image of a man they would like to identify and speak with.

He is described as Black and aged in his 30s or 40s. He was wearing a black beanie hat, black jacket and black trousers.

Anyone who recognises the man is asked to call police via 101 quoting reference CAD 278/27Jan. To remain anonymous contact Crimestoppers on 0800 555 111.
