A 36-year-old man was hit over the back of the head with a stool and punched repeatedly during an apparently unprovoked attack in a betting shop.

Police have released an image of a man sought over the attack on London Road in October.

The victim required medical treatment including gluing of the wound caused by the stool.

His attacker fled the scene after the incident, which happened at around 4.20pm on Thursday October 16.

DC Rob Wevill, from Croydon CID, said: "This was a violent assault on a man for no apparent reason.

"We would urge anyone who recognises the person in the image to get in touch with us with Crimestoppers, which is completely anonymous."

Anyone with information should call Crimestoppers on 0800 555 111, quoting reference number 111969.
