A SECOND man has been arrested for the machine-gun killing of Dean Tully in January.
Details of the brutal slaying on the Haverfield Estate in Brentford still remain shrouded in mystery four months on. But police have confirmed that a 37-year-old man was arrested on May 16 on suspicion of conspiracy to murder.
Mr Tully, 37, died of multiple gunshot wounds in a flat in Fraser House after two black men burst into the address at 9.22pm and opened fire with a machine gun. Another man, in his mid 30s, was also injured in the attack. He was treated at hospital and later discharged.
The recent development follows the arrest of a 23-year-old man in February. Both suspects have since been bailed until July, while police continue their enquiries. The machine gun has not yet been recovered.
Police are now preparing to release CCTV footage of two men taken near the scene of the murder in the hope of jogging the memories of potential witnesses and encouraging them to come forward.
Det Ch Insp Duthie said: "We do have some witnesses but we're still looking to talk to anyone who was in the vicinity or might have information about the men or the gun involved. This was a shocking incident, which we're pretty sure was drug-related, and we're anxious to get these people and this dangerous weapon off the streets.
"We're anxious to talk to anyone who saw anything out of the ordinary that day or who knows who the major dealers of class A drugs were on the estate."
Anyone with information should call the incident room at Sutton police station on 020 8721 4165 or Crimestoppers, anonymously, on 0800 555 111.
