A man shot dead by police in Northumberland had a homemade gun, an initial investigation has revealed.
A search of the scene revealed a homemade weapon
John Mark Scott, 42, died from a single shot fired by a police marksman in the village of Stocksfield on Saturday.
He had barricaded himself inside a house in Kimberley Gardens after being seen assaulting a woman in the street.
Northumbria Chief Constable Mike Craik had said applications for shotgun licences from Mr Scott had been revoked in the past.
The Independent Police Complaints Commission (IPCC), which is investigating the shooting, said a forensic examination of the weapon had showed it was capable of firing shotgun rounds.
Shotgun ammunition was also found in Mr Scott's house.
Mr Scott was shot after an officer on his way to an un-related incident saw him assaulting a woman near his Kimberly Gardens home.
Mr Scott discharged a weapon as the office intervened. The officer, who was unhurt, used CS spray to defend himself.
Armed response officers were called and a stand-off developed. A single shot killed Mr Scott when he appeared at an upstairs window with what appeared to be a weapon.
On Tuesday, Gary Garland, IPCC commissioner for the North East, said: "This is a desperately tragic incident for all parties concerned and my sympathies go out to Mr Scott's family at this difficult time.
"I also wish the injured woman a full and speedy recovery. In due course she will be interviewed as a significant witness to the incident.
'Establish the facts'
"Incidents such as this are incredibly difficult situations for the police. Armed officers have to use their professionalism, training and experience to make judgment calls of momentous significance in quick time.
"We rightly expect the police to provide protection to the public, but we also need to have confidence that police firearms are discharged appropriately and only as a last resort.
"For the sake of Mr Scott's family and the police officers involved I will ensure that our investigation will as quickly as possible establish the facts of what happened on Saturday."
A post-mortem was carried out by a Home Office pathologist revealed Mr Scott died from a single shot to his chest.
