A MAN on a bike sexually assaulted a girl and rode off.

The 17-year-old victim was walking past the Co-operative shop in Dyke Road, Brighton, on Tuesday (May 12) when the man approached her, grabbed her buttock causing her pain and rode off into Highdown Road.

A police spokesman said: “She shouted loudly at him as he did so and as there were a lot of people in the area at the time. We are hoping there may be a number of witnesses who have yet to come forward.”

The man is described as white, aged between 17 and 20, 5ft 8ins to 6 ft tall, skinny, and wearing a burgundy hooded top with orange and white writing, baggy jeans and black trainers.
