A brutal nightclub assault that began with a row about queue-skipping has been caught on camera - with crystal clear images of the suspects police want to track down.
A 25-year-old man was at the bard in The Watershed Nightclub in Wimbledon on 19th March when the three suspects approached him.
There was an angry exchange about queue-jumping before one of the suspects produced a glass and slashed the victim across the cheek, ear and forehead.
The two other suspects then punched and kicked him. The victim needed hospital treatment later, eventually being discharged with nine stitches.
The suspects are described as follows:
Suspect 1 is a tall, black man of medium build with short black hair and a short beard, aged in his 20s. He was seen wearing a black t-shirt with two buttons on the front, black trousers and black shoes. He left wearing a hooded jacket with a fur hood. He had tattoos over both his wrists.
Suspect 2 is described as a clean shaven white man of medium build in his 20s wearing light coloured trousers and t-shirt, black belt and black shoes.
