Police are advising residents to be on their guard after four recent burglaries in the Blyth area.
Officers investigating the offences believe the same person is responsible.
They were called to an address in Ingram Drive on Tuesday after an elderly resident had found an intruder in her house that morning at around 10.30am. He claimed to be looking for odd jobs.
A short time later, he went to a neighbour’s home and was again disturbed by an occupant.
There have also been similar reports of a man being disturbed by residents inside premises in both Matfen Close and Beal Close, which are currently being investigated.
The offender is described as being in his late teens to early 20s, approximately 5ft 4ins tall and having a slim build and scruffy looking appearance.
Detective inspector Sharon Chatterton said: “Our officers are carrying out house-to-house inquiries in the area and we would also ask anyone with information about these types of suspicious incidents to come forward and speak to police.”
Neighbourhood inspector Grant Dawson added: “We want to remind residents to be alert to this issue and make sure they keep their doors locked, to prevent anyone simply walking into their home, and report any suspicious activity.
“We would also like to ask members of the community to look out for elderly or vulnerable neighbours who could be victims of this type of crime and report any suspicious people or vehicles they see in their community to police. If in doubt, contact officers.”
Anyone with information about the burglary offences in Blyth should call police on 101 – quoting reference number 895 of 16/08/16 – or ring the independent charity Crimestoppers anonymously on 0800 555111.
