Police have released a picture of a man as part of their investigation into an arson attack on a Promenade shop.
Officers would like to speak with the man following the attack on Phat Freddy's on September 1.
Police also arrested a 22-year-old man on September 30 - and he has now been released on bail pending further enquiries.
A police spokesman said: "The man on the CCTV or anyone who can identify him are urged to call 101 quoting crime reference number or Crimestoppers anonymously on 0800 555 111."
Quick-thinking Jenny Boldrini used a garden hose to douse roaring flames at Phat Freddy's - seconds after the attack.
She had been working at the Golden Anchor Cafe adjacent to Phat Freddy's at the time.
She said:"I could smell it so I went around the back and someone had used rags and a petrol can to set the shop on fire. "There were just the remains of the petrol can, but it looked like it had spread under the door."
