Residents are being urged to secure their homes to stop sneak-in thieves following a number of thefts.
Northumbria Police has issued the advice after recent incidents of criminals taking advantage of insecure doors to raid properties.
Increased patrols are taking place in a number of areas while residents are also being asked to play their part.
Supt Mick Paterson said: “These latest incidents show how easy it is for thieves to access insecure homes. But they could have been prevented had the door been locked.
“While we will be carrying out increased patrols to target thieves, we need residents to help themselves from becoming a victim of burglary.
“Don’t give an open invitation to thieves and make sure doors are locked, even when inside your property.
“Simple things like locking your doors and removing keys from the lock, closing your windows or investing in a timer switch for your lights can make a real difference.”
