Police want to speak to this man about an attempted rape on a busy city street.

A 19-year-old woman was in St James's Street in Brighton when a man ran from behind her, grabbed her hair and attacked her at about 2.50am on Friday 19 July.

The victim bravely fought the attacker off and police are treating the incident as an attempted rape.

The grainy CCTV images show a man police would like to speak to over the incident.

He was clean shaven, white, in his 20s, 5'4" or 5'5" and slim but muscular. He had short blondish hair that was flat and brushed forward at the front.

He was wearing a white short-sleeved top with a pattern over the front with possibly blue and red colouring.

Police are putting out a new appeal in the hope of finding witnesses who may have left Brighton and Hove during the summer and did not see previous publicity about the attack.

Detective Inspector Lee Horner said: "We are determined to catch the man responsible for the attack and hope to get more witnesses who may have been away from Brighton and Hove during our last appeal.

"This was a terrifying incident for the victim who did well to fend off her attacker but has been left shocked and hurt by what happened.

"There may be witnesses in the city who may have seen what happened or could recognise the man in the CCTV but have been away from Brighton and Hove through the summer.

"If you know anything, no matter how insignificant you might think it is, please contact us."

Anyone with information should call 101 quoting serial 1625 of 19 July or the independent charity Crimestoppers anonymously on 0800 555111.
