William David Floyd was ejected from the pub and then later got into an altercation shortly before 10 p.m. Friday, police said.

Officers were called and found Floyd unresponsive when they arrived. Paramedics then rushed him to hospital, where he was pronounced dead.

The cause of death has not yet been determined, and the investigation is ongoing.

Police say they are treating his death as a possible homicide — making it the city's third homicide this year.

A 50-year-old man was taken into custody who they say was involved in the altercation, but no charges had yet been laid Saturday.

Anyone with information is asked to call the Vancouver police homicide unit at 604-717-2500 or Crime Stoppers at 1-800- 222-8477.
