Police are appealing for witnesses after a man was assaulted in Brighton.
Officers were called to East Street in the city centre at about 1am on Saturday (June 25) to reports of a suspected drink-driver who subsequently ran from officers but was subsequently detained.
A man aged 37 who was in the area at the time assisted officers in their attempts to detain the driver. Whilst doing so, he was assaulted by another member of the public, causing a serious injury.
He was taken to the Royal Sussex County Hospital, where he remains.
Officers have released images of two men they wish to speak to in connection with the incident. They presented themselves to officers at the scene but then left the area while officers responded to the injured man.
One of the men had a white T-shirt that appeared to be torn, while the second man wore a grey hooded top and black T-shirt.
The man who was arrested has been charged for unrelated offences.
Anyone who witnessed what happened or who recognises the two men is asked to report it to Sussex Police online or call 101 and quote serial 104 of 25/06.
