The first victim came face-to-face with an intruder in her home in Knipton, in the Vale of Belvoir.
She walked into her kitchen to find a stranger in his 30s in the room. When she confronted him, the man said he was looking for a blue ball.
While the woman went to fetch her husband from the garden, the man walked into the sitting room. He then left the house with two other men - one in his 30s and one older man with an Irish accent - in a dark blue car.
The couple went upstairs to find their bedroom had been ransacked and jewellery and family heirlooms had been stolen.
The burglary happened between 5.30pm and 5.45pm on Monday, May 11.
At 6pm the same day a resident in King Street, Scalford, heard a noise upstairs in her home.
Initially she thought it was her husband until he came in from the garden.
The husband went upstairs to confront the burglar who made up a story that he was working in the area and was there to check the family’s oil tank. He then left the house and joined other men.
When the homeowners checked upstairs, the rooms had been ransacked and all the cupboards and drawers emptied.
A Leicestershire Police spokeswoman said officers were investigating both incidents.
She urged anyone with information about the burglaries to call Leicestershire Police on 101 or alternatively to call Crimestoppers, anonymously and in confidence, on 08000 555 111.
