Vancouver police say officers seized 50 rounds of ammunition from a man during a recent sting using a bait bicycle.
Police say officers locked a bait bike in a rack in the city's downtown core on Sunday night.
The suspect broke the lock, removed the bike from the rack and walk off with it, but then officers arrested the 24-year-old, who police say is known to them.
Officers found tools and 50 rounds of ammunition during their search of the Vancouver resident.
About 3,000 bikes are stolen annually in the city, but hundreds can't be returned because police say their owners haven't recorded and reported the serial numbers.
Police have launched an online registry that tracks stolen bikes through their serial numbers.
