It may look strange if you spot it, and yet a few cardboard pieces carefully placed on doors of homes are the new methods that thieves are using to detect if there is anyone at home.
The Police have warned through their Twitter account, about new signs used by thieves to break into certain houses.
Using little pieces of cardboard and placing these in the main door of houses, the individuals then take photographs and will come back to check and find out if there has been any activity within the house. If someone enters or goes out, the pieces fall onto the floor.
Thieves use this method to confirm if anyone is residing there so they can break into the property.
