“Leigh-Anne’s friend wasn’t going to let it go. She kept saying ‘no I wouldn’t, no I wouldn’t’. And Leigh-Anne started going, ‘Maybe I would, maybe I would’."

They say he then told her friend to "shut up" and Leigh-Anne replied, "'Don’t say that to her’ or ‘don’t be rude.’"

The eyewitness added: "And he walked around the table and leant into her and gave her a clean slap on the face.”

Leigh-Anne was said to have been initially shocked before breaking down in floods of tears as her friends comforted her.

“Her friend had her arm round her. She looked a mess and she was crying her eyes out," the onlooker continued.

A Met spokesman said: “Police were called on Monday, 28 November at around 04:50 hours by a woman who stated that a man had threatened to assault her and had assaulted another woman she was with.

“The suspect made off prior to police arrival. Officers conducted a search of the area and did not locate the suspect.”

According to police, no arrests have been made and enquiries are on going.
