Two female police officers have died during a "routine" call-out which led to the arrest of a man wanted by Greater Manchester Police.
PC Nicola Hughes, 23, and PC Fiona Bone, 32, suffered fatal injuries in the incident in Mottram, Tameside.
Greater Manchester Police Chief Constable Sir Peter Fahy said it was one of the force's "darkest days".
A witness at the scene in Abbey Gardens reported hearing 13 gunshots and an explosion.
Dale Cregan, 29, has been arrested in connection with the officers' deaths and two previous murders. He was arrested when he walked into Hyde police station a short time after the incident.
Police had been offering a £50,000 reward for information leading to Mr Cregan's arrest. He was wanted over attacks that left Mark Short and father David (pictured) dead.
Police said one of the officers died at the scene and the second was critically injured and died afterwards.
The scene has been cordoned off and there is a heavy police presence in the area, including a bomb disposal team.
Sir Hugh Orde, president of the Association of Chief Police Officers, said the deaths of the two officers were "deeply sad news for the police service".
The flags outside Greater Manchester Police headquarters were lowered to half mast in response to the shootings of the two officers.
Police officers pay their respects as a private ambulance leaves the scene of the shootings in Mottram carrying the body of one of the dead officers.
