A policeman who died after being attacked while off duty has been named.
Pc Chris Findley suffered a serious head injury after becoming involved in a row during a night out in Wolverhampton city centre in the early hours of Monday January 28.
The 33-year-old, from Wolverhampton, died in hospital on Thursday night, West Midlands Police said.
Pc Findley was punched as he walked past the Divine Bar in Darlington Street after becoming involved in an argument with a black man and two white women who were leaving the nightclub.
The officer, who was left unconscious in the street, is believed to have been attacked at around 4.30am. A post-mortem examination has yet to be carried out to determine the cause of the officer's death.
His colleagues at West Midlands Police paid tribute to the officer, who was based in Sandwell.
Chief Inspector Paul Betts said: ""Chris was a proactive, hard-working officer who was a credit to the service and the communities of Sandwell. He will be sadly missed by all that knew him and our thoughts and condolences go out to his close friends and family at this difficult time."
West Midlands Police Detective Inspector Phil Asquith has appealed for anyone with information to contact them. He said: "They got into a fight moments after leaving Divine Bar and I'd appeal for anyone who was in the club that night and may have seen them to contact police.
"I'm also keen to hear from anyone who was driving along Darlington Street in the early hours of that morning, heading home after a night out, or perhaps taxi drivers, as they may have witnessed it. At the time they may have written it off as a low-level disorder but it's a very serious assault."
An 18-year-old man and two women have been arrested by police and bailed until a date next month pending further inquiries.
