Last week, Kent Police released a CCTV image of man who "may have important information" in connection with the death of Joe Daniels at the Red Cow pub in Foord Road, Folkestone.
Officers said yesterday (28 January 2018) they removed the image because they believed they had identified the man, and said the response to the appeal had been "excellent".
Daniels was found unresponsive inside his pub, which is part of the Ei Group estate, shortly before 11.30am on Wednesday 22 November last year.
He had suffered an injury consistent with a gunshot wound and was pronounced dead at the scene, with a firearm was recovered at the property, police confirmed.
Senior investigating officer, Detective Chief Inspector Richard Vickery, said: "Once again, we would like to thank all those people who have come forward with information so far.
"Witnesses can contact us through our appeal line on 01303 289600 quoting reference 22-0453 or Kent Crimestoppers anonymously on 0800 555 111."
According to Kent Live, bouquets of flowers were placed in tribute to the 58-year-old outside the pub after his death, with those who drank in the Red Cow describing Daniels as an "absolute legend".
