One of the country's most wanted men, Dale Cregan has handed himself in to police shortly after the incident which left two unarmed police officers dead.
PC Fiona Bone and PC Nicola Hughes were both shot and killed as they attended what Greater Manchester Police have described as a "routine incident."
Greater Manchester Police had been leading a huge manhunt to find Cregan, who was wanted for questioning over attacks involving grenades and guns that left a father and son dead.
The body of David Short, 46, was found at his house in Clayton, Manchester on 10th August after police responded to reports of gunfire.
Less than 10 minutes after his body was discovered there was another grenade blast and shots were fired at a house in Luke Road, Droylsden, but no-one was injured.
Mr Short's amateur boxer son Mark, 23, was killed in May when he was shot in the neck at the Cotton Tree pub in Droylsden when a gunman walked in and opened fire.
Three other men were shot during the attack and suffered leg and back injuries.
GMP had offered a £50,000 reward for information that would lead to the arrest of Cregan, 29, from Droylsden.
His image was also put on a big screen at Manchester City's Etihad Stadium to try to urge people to come forward with information.
Cregan, who only has one eye, was also wanted for questioning over the murder of Mark Short.
Four men have already been charged in connection with Mark Short's murder and are due to enter pleas at Manchester Crown Court in November.
After Cregan's arrest today Greater Manchester Chief Constable Sir Peter Fahy said that he believed Cregan had been harboured by others and said the investigation in to the deaths of PC Hughes and PC Bone would find those who had helped him.
