Sleeping householders are going to be woken up in the middle of the night to discover someone breaking into their house - only to discover it is the police.

Police in Shoebury, Essex, have been going round testing doors and windows of houses to check if they have been left unlocked - and if they find an easy way in they will wake up the household to warn them their house is insecure.

The new police campaign is aimed at warning people of the dangers of late-night break ins - but predictably, those who have been woken have not been happy so far.
