Police are warning homeowners in Gedling and Burton Joyce to be on the alert following a spate of burglaries in the area over the past fortnight.
Police say most of the offences have occurred in the afternoon or evening with offenders entering the properties through rear doors or windows.
In a recent burglary in Burton Joyce, the offender smashed a rear window to access door keys which had been left in the lock on the inside of the door by the occupant.
In all the offences, electrical items and jewellery were stolen.
Local neighbourhood inspector Andrew Berryman said there are measures the public can take to make life difficult for thieves.
He said: “Please ensure that you secure your property, even when at home, and remove keys from doors and windows. When possible, make your property look occupied when not by leaving lights on, and using timers to put televisions and radios on. Timers can be purchased from a number of outlets cheaply.”
Detectives are investigating all these offences and are keen to hear from anyone who may have information as to who may be responsible. Please contact Nottinghamshire Police via 101 or Crimestoppers anonymously on 0800 555 111 with any information.
