Thunder Bay police have a new worry. Monday night they seized a pen sized emergency signal flare which was modified to shoot a .22 calibre bullet. Sgt. Rino Belcamino is issuing a warning about the safety of the device. He says not only is it dangerous to the person it's being pointed at, but people who modify it are risking their own safety. .Belcamino says police are starting to see such converted devices more and more.
