Four burglars smashed a panel in a conservatory door in a brazen daylight raid on a home in Queens Court in Bicester on Saturday.
The men stole a Louis Vuitton purse, cash, a credit card, and jewellery before an alarm sounded and the group fled the home.
Police said the men would have been highly visible as they ran down Queen’s Avenue near Bicester Magistrates’ Court following the break-in at 4.50pm.
They got into a large silver or grey BMW, which had been parked next to Bicester Health Centre in Coker Close, which then drove off towards the A41.
PC Bryn Smith, of Banbury Police Station, said: “Queens Avenue and Kings End were very busy at the time of the burglary, with both vehicle and foot traffic. “The four offenders were highly visible and would have looked out of place.
“I would appeal for anyone who saw this incident or any person matching the description of the offenders or the vehicle they used to get in contact.”
All four were white men.
One was around 6ft tall and of muscular build, and was carrying what appeared to be a golf club with a sock on the end.
The other three men were around 5ft 6ins tall and slim.
The stolen jewellery was described as a pair of diamond and black pearl platinum earrings, and an 18 carat gold diamond ring.
Anyone who saw the men or has information regarding the burglary should contact PC Smith at Banbury Police Station via the Thames Valley Police Enquiry Centre on 101.
