A man was left with facial injuries after he was robbed in Oxford by a gang of youths.

The gang attacked the 55-year-old man as he was walking near the Q8 garage in Oxford Road, Cowley. The attack took place at 10.50pm on Friday.

Four youths pushed the man to the ground, leaving him with a grazed face, and stole his wallet.

Two special constables, who were carrying out a traffic operation nearby, helped the man.

They later arrested three youths at the scene, one aged 14 and two aged 15.

All three have been released on bail.

Police are appealing for witnesses to help trace the fourth youth, aged about 15, involved in the attack.
