A man was assaulted and robbed as he walked up Blatchington Hill in Seaford, early on Sunday morning.
Police are appealing for witnesses after the 23-year-old victim was approached by a man between 1.35am and 2am as he walked away from the town centre.
He assaulted the victim and demanded his phone, wallet and PIN number for his bank card. He then made off with the mobile phone, wallet and bank card.
The victim received minor injuries to his face and chipped teeth.
The suspect is described as white, aged about 19 or 20, with short, clippered hair, about 5ft 5in tall, fat and spoke with a southern accent. He was wearing a dark, plain zip up hoodie and dark blue jeans.
Detective Sergeant David Tye said: “We are seeking any witnesses to the incident or anyone who recognises the description of the man involved in the attack. The phone stolen is an old Sony Ericsson Elm handset, with very little resale value, which may have been dumped by the attacker.”
Anyone with information should contact Sussex Police on 101 quoting serial 0159 of 16/12.
