The Independent Police Complaints Commission (IPCC) has launched an investigation following the death of a man after he was tasered by officers.
Police had been trying to arrest Dale Burns on suspicion of causing criminal damage at his flat in Barrow-in-Furness on Tuesday night.
The 27-year-old was tasered several times and sprayed with pepper spray during the attempted arrest.
He was taken to hospital but pronounced dead. A post mortem is due to be carried out as soon as possible.
Cumbria Police said officers were called to an address on Hartington Street in Barrow on Tuesday evening following reports of a man causing a disturbance.
The IPCC said: "Police attempted to arrest the man on suspicion of causing criminal damage at the flat.
"During the arrest one officer discharged a taser at the man a number of times.
"Another officer deployed Pava spray (commonly known as pepper spray). The taser deployed is understood to be a conventional police weapon."
