A police officer has been left seriously injured after plunging through a garage roof while trying to detain a suspect.
Pc Christopher Hardaway, aged in his 20s, sustained serious head injuries when he fell through the roof of a car mechanics' premises in Hampton Road, Redland, Bristol, this morning.
The Avon and Somerset officer was patrolling the area with a colleague when they noticed a man who appeared to be acting suspiciously.
The police helicopter was called in to assist the search and reported that a man was on the roof of the Bristol 2CV garage. Pc Hardaway climbed on to the roof in search of the man but fell through it.
He was transported to Frenchay Hospital, where he remains in a critical condition.
Pc Hardaway's actions were described as "brave and courageous" by Assistant Chief Constable Anthony Bangham.
"This kind of feat is part and parcel of the daily business of our officers," he said.
"We are proud of Christopher, who is typical of the enthusiastic men and women who police in Avon and Somerset, patrolling the area with courage and integrity making people feel safe in their homes.
"Christopher has been seriously injured and is undergoing emergency surgery and our thoughts are with him and his family at this time, as they would be for any other officer injured carrying out actions to protect their local community."
The scene remains cordoned off for a forensic examination and officers will be carrying out door-to-door inquiries in the area.
Police are appealing for witnesses to come forward that may have information on the suspect, who is thought to have dark hair and was wearing dark clothing.
"We would like to hear from anyone who may have been in the area at the time who may have seen anything to help the police inquiries," a force spokesman said.
Anyone who may have information is advised to contact Bristol CID on the force number 101.
