A man has been seriously injured and remains in critical condition following an arrest attempt made by Vancouver Police officers on Thursday.

The Independent Investigations Office of B.C. has been notified.

Officers were called by staff at an SRO near Hastings and Dunlevy just before 12:30 p.m., asking for police assistance to remove a man from the building.  Officers were made aware the man had a BC-wide warrant.

While they attempted to speak to the man in the hallway of the building, witnesses saw him fall from his window. The 25-year-old man was taken to hospital with life-threatening injuries.

The IIO BC is now the lead agency investigating the incident.
