The victim of a sexual assault on a bus in Beckenham has said the attack has left her feeling "violated".

The early morning attack was on December 12 last year, at around 7.15am, on the Route 54 bus heading towards Lewisham.

The 25-year-old woman sat on the upper deck of a virtually empty bus but at the very next stop, the suspect boarded and sat directly next to her.

The suspect first started to try strike up a conversation, then put his arms around her and grabbed her breast.

This prompted the woman to push the suspect away, run down the stairs and off the bus.

The suspect is described as a black man, aged between 20 to 25-years-old of slim build. He was wearing a blue baseball cap, dark jacket and scarf around his mouth.

Police Constable Jay Thorn, who is investigating the assault, said: "This has left the victim feeling violated and now anxious to use public transport.

"I would urge anyone who recognises the man wanted for questioning to contact us as soon as possible."

Any witnesses or anyone with information is asked to contact police on 0207 327 4444 and quote CAD 1391/12Dec.
