Police are appealing for witnesses after two men were robbed at around 10.30pm on Saturday, March 15.
The pair were approached by a black man who stole a box of beer - possibly Budweiser - from them.
The theft is being investigated as part of a wider incident that occurred in the same area on the same evening, and for which a man was arrested, questioned and later bailed.
Detective Constable Clare Thomas, of Worthing CID, said: “ If you are one of the two men who were approached, or if you know who they are, I would like to talk to you. Please phone Sussex Police on 101 or email firstname.lastname@example.org, quoting serial 1494 of 15/3.”
