Burglars stole an Audi A3, handbags and cash after they raided two properties in Pitsford.
One of the burglaries happened between 11.30pm on Monday and 7.20am on Tuesday at a house in Broadlands when thieves broke in through a ground floor window and stole various items including handbags and cash.
Officers believe this is linked to a burglary at another property in nearby Manor Road, where thieves broke in between 1am and 7am. They took various items, including a handbag and a set of car keys to a white Audi A3, which they also stole.
