A man has been shot dead by police after officers were sent to an address in Carlisle.
Armed officers were called at 3.37pm on Monday to Borland Avenue to reports of a person threatening people.
They found a man in possession of a knife, Cumbria Constabulary said.
The man, in his 40s, was shot by police and suffered fatal injuries. He was pronounced dead at the scene.
A statement from Cumbria Constabulary said: “No other members of the public were injured during this incident, which at this stage is believed to be an isolated incident.
“A cordon is in place at the address as officers conduct their enquiries. We would ask members of the public not to attend the scene.
“There will be increased patrol activity within the Botcherby area throughout the night to help reassure and support the local community.”
The Independent Office for Police Conduct (IOPC) is investigating the incident following a mandatory referral by Cumbria Constabulary.
“Our investigators are attending the scene and the police post incident procedures, where the officers involved will be providing their initial accounts”, the IOPC said in a statement this evening.
“The IOPC investigation is at a very early stage and no further information can be provided at this time.
“Our thoughts are with all those affected by this tragic incident.”
