Murder investigation launched after fatal stabbing

A man has been arrested on suspicion of murder after allegedly stabbing another man to death.
Emergency services were called to a property in Bedford Street in central Gloucester at about 07:40 BST.
Three men were taken to hospital, Gloucestershire Police said, one of whom died at about 12:00.
The suspect, in his 30s, was arrested by armed police a little more than a mile away from the scene, in Chequers Road, at about 08:10. He was also taken to hospital for treatment.
He has since been discharged and transferred to police custody.
The man who died has not been formally identified, but investigators have said they believe they know who he is and his family have been informed.
The two other victims remain in hospital but their injuries are not thought to be life-threatening.
Assistant Chief Constable Arman Mathieson said the suspect and the victims are believed to be known to one another.
"We understand how alarming and distressing this incident has been for members of our community," he said.
"We would like to reassure everyone that the incident was contained within the address and there is no ongoing threat to the wider public."
He said there would be an increased police presence in the area in the coming days.
A cordon remains in place and investigators are appealing to anyone with information to contact them.
