TAXI drivers could hold the key to a murder investigation.

Posters have gone up at cab ranks in the hope of tracing the final movements of a 21-year-old man who was stabbed to death last month.

Sussex Police are hoping to find a taxi driver who may have driven Albanian Serxhio Marku on the day he was killed.

The posters have appeared at East Street taxi rank in Brighton.

They appeal for drivers who may have picked up Serxhio – and possibly some friends – and taken them to the Seven Dials area.

The poster said: “He may have used a taxi on Tuesday 10 or Wednesday 11 September.

“Queen’s Square or central Brighton was the likely pick-up point.

“Drop-off location was at Seven Dials.”

Serxhio was found, critically injured, by officers at a ground floor flat in Stafford Road.

He died en route to the Royal Sussex County Hospital in the early hours of Wednesday, September 11.

It is hoped that the driver who took Serxhio to Stafford Road may hold information vital to the investigation.

Chefs Francesco D’Agostino, 44, of Stafford Road, Brighton, and Giuseppe Petriccione, 45, an Italian national of no fixed address, have both been charged with Serxhio’s murder.

Detective Chief Inspector Alex Geldart previously said: “I am particularly keen to reach out to Serxhio’s friends in the Brighton area as we know very little about him and we want to find out where he lived and who he associated with locally.

“We believe that he may have travelled from the city to the Seven Dials area, and possibly on to Stafford Road, by taxi during the evening before he was attacked.

“He may have been with two other men and we would like to hear from the taxi driver who carried that fare.

“Specialist family liaison officers are supporting Serxhio’s family, who are mainly in Albania, and our thoughts are with them and his friends.

“I urge anyone with information about the incident, events leading up to it or especially about Serxhio himself, to report online or call 101 quoting Operation Barnfield.”
