Jamie Tipper death: Avon Gorge cliff face to be searched
A specialist "rope access" team will be brought in to search the cliff face at Avon Gorge where a man died following a fall in December, detectives have said.
The death of Jamie Tipper, 23, is currently being treated as unexplained.
Det Insp Andy Bevan said they were also trying to identify four people, including a taxi driver, who could have vital information.
A 24-year-old man arrested on suspicion of murder following his death remains on police bail until mid-March.
Mr Bevan said: "We've received further information relating to the death of Jamie Tipper which has resulted in us calling in the rope access team to help with a search of the cliff face at Avon Gorge on Sunday.
"The team has been tasked to look for specific items relating to the inquiry."
He said they were also trying to identify a taxi driver who is believed to have been on the Circular Road on Clifton Down between 19:00 and 19:30 GMT on 20 December.
"We believe a member of the public spoke to the taxi driver shortly after Jamie fell to his death and we are yet to trace this taxi driver," Mr Bevan said.
"In addition, we're trying to trace two men seen walking in the Circular Road area around the time Jamie fell - one was smoking a cigarette while the other was seen near the cliff-edge warning sign.
"These people may hold important information and I would urge them to come forward.
"We're keeping Jamie's family fully up-to-date with our progress. They're devastated at their loss and are understandably desperate to know the full circumstances surrounding his death."
Officers from Avon and Somerset were called to Circular Road on Clifton Down at about 19:30 on 20 December after reports a man had fallen.
The body of Mr Tipper, of Old Market, was found a short time later near the Portway.
