If you ever see a person pedaling with two bikes follow them. 99% chance it's stolen. Third time I've captured a stolen bike. The last time I turned around when driving a fire engine and called out over the PA for him to drop the bike, an almost new pearl colored Schwinn beach cruiser girls bike. And NEVER turn it over to the police. Give them the serial number and hold on to it. The rightful owner can pick it up from your house after describing it. Police aren't attentive on locating the owners and the booty ends up getting sold off at public auction after a couple of years.
