VANCOUVER -- A collection of wigs worth more than $350,000 that was intended for cancer patients at BC Children's Hospital has been stolen from a store in Vancouver.

Police say at least 150 wigs worth about $2,500 each were taken from Eva and Company Wigs on Friday morning.

Officers responded to an alarm at the store on Vancouver's west side at 3:30 a.m. and discovered the theft.

Police say they are looking for a man with long curly black hair.

He was last seen walking away from the store carrying a large black garbage bag and wearing a denim or blue jacket.

Sgt. Jason Robillard says police need people to come forward with information.

"It's possible that someone is in possession of one or more of these wigs, and that they don't know they're stolen or that they were meant for sick children," he said in a news release on Tuesday.
