Police in the Canadian province of Alberta say an officer who was recruited from Britain has been shot dead.
Edmonton Police Chief Rod Knecht confirmed the death of Constable Daniel Woodall (38), an eight-year veteran of the force who worked for the hate-crimes unit. He had served with Greater Manchester Police.
A 38-year-old officer was also shot in the back but was saved by his bulletproof vest.
Mr Knecht said the two officers had been delivering an arrest warrant for when they came under gunfire.
A fire erupted at the home soon after shots were discharged, and police in a message posted overnight on Twitter said they were no longer looking for a suspect.
