A man was allegedly stabbed in a Soho street after a row broke out in the queue for a pop-up event by American singer Latto.

The victim, a man in his 30s, was treated for stab wounds to the leg after the incident in Greek Street, Soho, at around 4.30pm on Thursday.

Angela Dean, a witness in her 50s, said 'chaos erupted' as she queued with her 14-year-old son.

She said people attempted to jump the queue and she captured footage of the incident.

A video appeared to show two men involved in a confrontation, with one holding what looks like a knife.

Angela, a full-time carer from Essex, said: 'Everyone was running and pushing - there was no crowd control.

'I had to run out of the queue to alert the bouncer at the club to what was happening.

'My child has been left deeply traumatised by what he witnessed.'
