Police are appealing for help to trace a man who assaulted a woman after she ignored him inside a busy City bar.

The victim, a 20-year-old woman, was having a drink with a friend inside B@1 on Brushfield Street, Spitalfields, when they met a group of a men whom they maintained company with for the rest of the evening.

At about 11pm the women were approached by one of the men but they paid little attention to him as they were engrossed in conversation.

A City of London Police spokesman said the man “became agitated” as he tried to get their attention.

“He then lashed out and threw both his drinks at the women, hitting one of them in the face with a glass in a seemingly unprovoked attack,” he said.

The man is described as white, slim build with short dark hair, wearing a light coloured shirt and suit with black shoes.

Anyone who recognises the man or witnessed the attack on Wednesday April 2 is asked to contact DC James Harris from the City of London Police on 0207 601 2222 or email james.harris1@city-of-london.pnn.police.uk.
