A man from Laindon was attacked with a monkey wrench after a fight with five men broke out in an off licence last Saturday.
The 34-year-old victim entered the Pints and Litres off licence at the Laindon Centre, Laindon, around the same time as the five men, and an argument with one of them occurred when they both went to the fridge.
The five men then attacked the victim, knocking over a 46-year-old female shop assistant in the process, continuing the fight outside using bottles and a monkey wrench, which the men got from the blue Peugeot 206 they arrived in.
Investigating Officer Dc Angela Tappin, of Basildon CID, said: "This appears to have been an unprovoked attack where a woman was pushed over and badly bruised so the suspects could get to the man who was assaulted. He received a nasty head injury."
Police are investigating the serious assault and have released CCTV images from the shop in a bid to identify the men.
Anybody who recognises them is asked to contact Dc Angela Tappin at Basildon CID on Essex Police 101 or they can leave information anonymously via Crimestoppers on 0800 555 111.
