A man who tried to intervene in a fight had his throat slashed.
Revellers at The Corn Exchange on Hailsham High Street were left horrified by the attack, which took place at around 1.30am yesterday.
The 52-year-old victim was taken to the DGH with what police thought were life-threatening injuries but remained in a stable condition. The blade used during the attack hit an artery in his throat.
Police are now looking to speak to 29-year-old Lucas Lamb in connection with the attack. Mr Lamb, from Hailsham, is described as white, 5ft 8in, of medium build, with dark brown hair and blue eyes. He was wearing a blue shirt
Officers would also like to speak to the driver of a BMW which was seen driving away from the scene shortly after the attack.
He is said to be white, in his mid to late 20s, between 5ft 8in and 5ft 9in tall, large build and wearing a black vest top, blue jeans and a gold chain. He has tribal tattoos over both shoulders and arms and has a v-cut hairstyle.
Police spokesman Detective Inspector Mark O’Brien said, “We have no reason to believe that the people involved are a danger to the general public and it seems that the incident may well have been between men who were known to each other.
“Police are keen to speak to anyone who may have information leading to the location of Lucas Lamb or the identity of the driver of the BMW.”
Anyone with information should call Sussex Police on 101.
