Vancouver police are seeking a "woman of interest" in an incident last month that caused $1-million damage to a downtown hotel.

Sgt. Randy Fincham said the damage happened in the evening of Sept. 30 when someone turned on a water pipe meant to be accessed by firefighters in case of an emergency.

"Police believe she was leaving a party or event at a private residence," he said.

Fincham, who did not release details about the hotel involved, said the water "caused significant damage to the building."

Fincham didn't know how long the water was left on for.

Anyone with information is asked to call Crime Stoppers at 1-800-222-8477.
