A man from Greater Manchester who stabbed himself and was then Tasered by police has died.
Officers were called to Salford Road in Over Hulton, Bolton, on Tuesday evening to reports that a man had barricaded himself inside his home.
They broke into the house and were threatened by the man, who had stab wounds to his stomach, a police spokesman said.
The 53-year-old was taken to hospital but died shortly afterwards.
A post-mortem investigation is due to be carried out later.
Greater Manchester Police's professional standards branch is investigating and the force is due to make a referral to the Independent Police Complaints Commission later.
