A computer, credit cards and £15 in cash were among items stolen in a series of burglaries in villages around Waddesdon.
Police believe the five burglaries, which took place between March 24 and 27, could be linked and have appealed for anyone with information to come forward.
Between 9pm on March 24 and 5pm on March 27, thieves broke into a home in Grendon Road, Kingswood, by using a crowbar to force open a front window. Jewellery and £15 in cash were taken.
Another Kingswood home, in Bicester Road, was also targeted at some time on March 25. Offenders smashed a kitchen window to get in but it is not known at this time if anything was taken.
Credit cards were taken from a house in the same road between 1pm on March 25 and 6.50pm on March 27. The thieves smashed a side kitchen window, ransacked the property and stole the cards.
A home in Ludgershall Road, Brill, was targeted between 8am and 4.45pm on March 25, with criminals breaking in through a PVC door and stealing a computer.
The fifth burglary was in Fleet Marston between 11am on March 25 and 1pm on March 27. Thieves smashed a rear bathroom window but left empty handed following a messy search.
Det Con Emma Francis said: “We believe these burglaries could be linked and if anyone witnessed them or has any information that could help us with our enquiries please contact us.”
