Post box set alight
Letters and cards have been damaged after someone set fire to a Banbury post box.
It happened on Ferndale Road on Bretch Hill just after 1pm on Thursday 8 April 2010.
Police are trying to find people who may have seen someone running away at that time.
A collection of eight letters and cards were damaged in the fire. Royal Mail have sent them to their Return Letter Centre, where they're being opened to see if there's a sender's address inside.
If one is found, the letter will be returned in a plastic bag explaining the condition and the cause.
Royal Mail are asking people concerned mail they have sent may be involved, to get in contact with them.
A spokesperson for the company said: "Acts of vandalism such as this are relatively few but where they do happen we take them extremely seriously.
"Every item of mail is important to us and we would encourage anyone with information about these incidents to contact the police. Any customers concerned can call Royal Mail Customer Services on 08457 740740 ."
