A Kettering home was burgled overnight earlier this week while the occupants were sleeping.
Some time between midnight and 4am on Tuesday, June 16, a property in Nelson Street, Kettering, was broken into.
When one of the occupants got up for work at 4am, she noticed a rear window was open and closed it before she left.
Later, when the other occupants got up, they discovered a wallet with documents, bank cards and cash had been stolen.
Northamptonshire Police would like to hear from anyone who may have witnessed the incident or may have seen anyone acting suspiciously in the area between the stated times.
