The Mounties say the mayhem started early Sunday morning at shopping mall in Burnaby, where the suspect drove a stolen Jeep SUV and then a stolen moving van into six marked police cars.
A news release says the man was arrested and taken to hospital for a psychiatric assessment.
But while at Burnaby General Hospital, the man pulled out a sprinkler head, causing the facility's fire sprinkler system to activate and flood the emergency room.
The hospital's emergency room was closed for part of the day on Sunday, with incoming patients diverted to other health-care facilities.
The RCMP say they're also looking into another incident on Saturday, in which someone at a health-care facility in Surrey became agitated and broke off a sprinkler head, causing water damage to the building.
The suspect in that case is believed to have driven away in a Jeep SUV.
