Jersey Police have released CCTV images of a man they want to identify in connection with a robbery in the Millennium Town Park on New Year's Day.
The victim had a gold chain, watch and mobile phone taken.
It happened outside the Gas Place cafe at around 6am on 1 January.
Police issued a witness appeal earlier this month.
It said there had been an argument, and the victim has walked off but was followed by the suspect and assaulted.
His shoes were also taken, but later found in the park.
The suspect was riding a bike and was wearing a dark top with a white collar and the word 'Spartans' printed across the chest.
Anyone who recognises the man in the CCTV images should call the States of Jersey Police on 612612 or Crimestoppers anonymously on 0800 555 111.
Alternatively, you can make a report online using the 'caught on camera' section of the Jersey Police website.
