A gunman has died after apparently shooting himself in the head following a 16-hour stand-off with police.
Paramedics spent more than three hours trying to save the man after at least one shot was fired on Leagrave Common, in Luton.
Eyewitnesses said the man was holding a sawn-off shotgun to his chin before the blast rang out shortly before midday on Monday.
Bedfordshire Police said one marksman may have also discharged a shot during the confrontation.
A spokesman said the man was pronounced dead by doctors at the scene some time after 3pm.
He said: “We confirm that the man involved in the shooting incident in the Sundon Park Road area of Luton has been pronounced dead after being treated at the scene.
“It would appear at this time the man discharged a weapon on himself, a shotgun has been recovered at the scene and it appears that it was in his possession at the time.
“The incident has been referred to the Independent Police Complaints Commission (IPCC) and Bedfordshire Police are co-operating fully.”
