Detectives investigating the brutal murder of Brentford man Dean Tully have arrested another suspect nearly two years after he was gunned down.
No one has ever been charged with the death of Dean Tully, who was killed on January 25, 2007, by two men who burst into a flat in the
Haverfield Estate and indiscriminately sprayed the room with bullets.
But the latest arrest, on January 9, brings the total number of suspects who have been questioned about the murder to four.
"We have made four arrests since Mr Tully's death twoyears ago and remain committed to solving this," said Det Ch Insp Mick Duthie, of the Serious Crime Command. "The case is still very much open. But we need the help of witnesses and the local community to help us actually bring charges."
Officers remain convinced the 37-year-old's death was the result of a turf war between rival gangs dealing Class A drugs in the Brentford tower blocks.
Our exclusive picture shows the Czech Republic CZ25 sub-machine gun which killed Mr Tully. Officers recovered the weapon last month after a gang of men were seen waving it around in a night club, in Streatham, south London. he suspects, who have since been charged with weapons offences, ditched the gun in a nearbygarden but it was discovered by an elderly lady who handed it over to the police.
At least nine people were also present at the two-bedroom flat in Fraser House when Mr Tully died. The property was used by various drug users and transient people, and officers do not believe the dad-of-one was deliberately targeted by the shooters. Another man and a Staffordshire bull terrier were also injured by bullets.
DCI Duthie said: "There is nothing in Dean's background that would lead us to believe he might have been deliberately killed. It seems he was just in the wrong place at the wrong time."
The investigation continues but officers admit they are still struggling to get the information they need from potential witnesses. A £20,000 reward offered for information remains unclaimed but is still on offer.
DCI Duthie said: "I'm anticipating making further arrests in the near future. But we need more people to ome forward. Someone out there, probably in the Hounslow or Ealing area, knows who is responsible and I would urge them to come forward.
"It's understandable if they're afraid but we can protect them and their information could be enough to secure a conviction and finally close this case."
Mr Tully, whose son was just 11 when he died, was shot by two balaclava-clad intruders at 9.22pm and pronounced dead at the scene.
Two black men, wearing dark clothing, entered the block through a rear fire escape, kicked down the door to Flat One and sprayed the room with bullets for three minutes.
The killers were then caught on CCTV fleeing down Green Dragon Lane. Police are still offering the reward of up to £20,000 for information leading to the identification, arrest and prosecution of the people responsible.
