Police are urging residents in Thurmaston to be vigilant after a spate of suspected attempted distraction burglaries.
Since Saturday, February 16, there have been six visits to two addresses on Humberstone Lane.
Elderly residents have been targeted by a man and a woman claiming to know the occupants or wanting to use their toilet.
Once inside the homes they have been challenged and left but returned on other occasions.
The man involved is described as white Eastern European, aged between 40 and 50 and of a stocky build. The woman is described white Eastern European, in her late 30s to early 40s with dark hair.
Pc Martin Sneath said: "Thankfully nothing has been stolen during these visits but it is worrying that these people seem to be targeting elderly people and seem to be persistent in returning.
"We need to catch those responsible and urge the public to help us. Were you visited in similar circumstances recently or do you remember seeing these people acting suspiciously in the area?
"Any information, no matter how insignificant it may seem, could help with our enquiries. Any calls received will be treated in confidence.
Anyone with any information is asked to contact Pc Sneath on 101.
