Police are searching for four men who fled a Bicester home in a VW Passat after being disturbed by the homeowner on Saturday evening.
The group forced open the front door of a home in Ravenscroft, Langford Village, shortly before 8pm while the occupants were in the back garden.
They searched the downstairs of the house before they were disturbed. The burglars left in a black VW Passat around two or three years old.
All four offenders were white men aged in their early twenties.
PC Kelly Thorogood-Gates from Bicester police station said: “I urge anyone that saw anything suspicious in that area to make contact with police, whether it be suspicious vehicles or people.
“There was a dog walker that may have seen the car and I would like them to come forward.
“I would like to stress the importance of keeping items hidden and keeping car keys away from open windows or doors.”
Anyone with information should contact PC Thorogood-Gates via the Thames Valley Police Enquiry Centre on 101, or Crimestoppers anonymously on 0800 555111 or online at crimestoppers-uk.org.
