Police are appealing for witnesses to or information about three unconnected robberies in the county on Saturday.

In the first incident a 77-year-old woman had her handbag snatched by two boys, believed to be about 12 or 14 years old, as she was walking along a pathway to the Blessed Dominic Barberi Church in Cowley Road, Oxford, at about 5pm.

After she called out, police said a 'good Samaritan' called Wayne stopped his car and chased the boys, later returning with the woman's handbag, nothing having been taken.

Police say they would like to speak to Wayne as he may have information which could identify the boys.

In Wantage, a 72-year-old man walking along Maryfield was hit over the head several times and knocked to the ground by a robber who then stole his bank card and cash.

Police said the elderly man was left badly shaken, but was unable to provide a description.

Police believe he may have been followed after leaving Rowes Newsagents, in Wallingford Street, and want to speak to anyone who may have been in the area at the time.

In Didcot, a 20-year-old man was punched to the ground and kicked repeatedly by a group of five men in Mereland Road, at 2.45am on Saturday. They took his watch and rings from his fingers.

One of the offenders was white, about 5ft 8in tall, skinny, with protruding teeth and a square jaw.

Anyone with any information on the three attacks is asked to call police on 08458 505505.

Alternatively call Crimestoppers on 0800 555111.
