A man shot with a Taser gun by police has died in Manchester after suffering what officers described as a "medical episode".
Officers shot the 23-year-old with the stun weapon in the neighbourhood of Gorton following reports of a disturbance involving a man with a knife.
According to local sources, the young man lived with his parents in the area. A neighbour told the BBC they were "a nice family who kept themselves to themselves".
The Independent Police Complaints Commission are investigating.
Assistant Chief Constable Garry Shewan said: "Police received a 999 call reporting a disturbance on Beard Road in Gorton where there was a man with a knife.
"Officers were dispatched immediately and arrived in eight minutes.
"On arrival, a Taser was discharged to detain a 23-year-old man.
"At this time it is unclear what happened, but at some point afterwards the man suffered a medical episode.
"Paramedics performed first aid on the man at the scene before he was taken to hospital where he sadly died.
"Greater Manchester Police has reported the incident to Her Majesty's Coroner and to the Independent Police Complaints Commission, and is working with them to establish the full circumstances that lead to the man's death.
"Specially trained family liaison officers are supporting his family during this very difficult time."
