Police are asking for help identifying several suspects who appear to be targeting homes in Niagara on the Lake.
Police say two suspects go to houses during daytime hours, when no one is home.
They knock on the door and if the homeowner answers, they make up an excuse or ask to use the phone, then leave.
If no one answers, the thieves break in and help themselves to small items such as jewellery or cash, anything that can be easily concealed in bags.
A third individual in a vehicle circles the block and picks them up when they are done.
Police are asking anyone who sees a suspicious vehicle or individuals to call them immediately.
