Burglars stole a number of electrical and sentimental items after breaking into a house in Corby.
The incident happened in Grantham Walk, some time between midnight and 9am on Sunday, October 9. The family were asleep at the time.
The offenders stole a number of electrical items, including mobile phones, computer consoles, tablets, laptops and bank cards.
The family are particularly upset about the burglary because the offenders stole a black leather wallet with a gold embossed message on the coin section, saying “To Granddad from Olivia and Chase”.
The stolen wallet also contained a picture of Olivia when she was born.
A police spokesman said: “This is an item that cannot be replaced and has great sentimental value.”
