Nine Bailed Over Double Shooting
Nine people, including two 16 year-old boys, arrested over the shooting of two "innocent bystanders" in north London have been bailed.
One of the victims of the shooting in Wood Green died of a gunshot wound to the chest, Scotland Yard said, while an unnamed 51-year-old woman remains in a critical but stable condition in hospital.
Detectives believe the two victims were not the intended targets and were probably bystanders who were not known to each other.
Three men and three women aged 16 to 61, arrested on suspicion of either murder or conspiracy to murder at Gatwick Airport on Tuesday, have been bailed, along with three men aged 23 to 55, who were arrested in Hornsey, north London, on suspicion of murder.
They have been bailed to dates in mid-September.
Detective Chief Inspector Tim Duffield, of the Homicide and Major Crime Command said: "The investigation is moving at a fast pace and whilst exact details of what happened remain to be established, what is clear is that two innocent bystanders have been caught up in a violent dispute between other people.
"I would like to take this opportunity to appeal to anyone who has information and has not yet come forward and spoken to the police to do so.
"I believe there are people out there who know who is responsible for this terrible crime and I appeal to them to consider how they would feel if their loved one was killed or seriously injured whilst going about their business.
"I would like to reassure anyone concerned about contacting the police that they will be treated with the utmost sensitivity and there are measures that can be taken to protect you."
The incident happened at 5.45pm on Friday July 10, just outside the Bros Bakery in Lordship Lane where Mr Guzel would often sit, eyewitnesses said.
Police are asking anyone with information to call the incident room on 0208 358 0400.
