POLICE are working with neighbouring forces as they investigate a series of ram raids across Oxfordshire.

On Monday it was revealed a 37-year-old Carterton man had been arrested on suspicion of burglary following the ram-raid style offence at Waitrose in Oxford on Sunday.

He has since been released under investigation.

Police are continuing to investigate this and other similar crimes that have taken place in the county in recent months.

In addition to the Waitrose incident, there have been five other similar offences in the county since December, including at supermarkets in Carterton, Grove and Charlbury.

Police are unable to confirm a connection between any of the raids at this stage and say they are keeping an open mind.

A spokesman said: "Thames Valley Police is investigating these offences as a crime series and the force is working with partner agencies and neighbouring police forces to ensure a robust response.

"These types of crimes are often very well organised and have previously been committed by organised crime groups from around the country, however we are keeping an open mind regarding who the offenders are in these particular offences.

"There has been an increase in burglaries where ATMs are targeted, this could be due to the fact there are now more ATMs, not just in banks but in shops and petrol stations."

Witnesses should call 101.
