A passer-by came to the aid of a man who had just been mugged and helped him retrieve his belongings.

A 23-year-old man got off a bus in Marsh Road, Cowley, Oxford, in the early hours of Monday and noticed two people walking behind him.

As a man grabbed his arms, a woman rifled through his pockets and stole a mobile phone and wallet.

The victim, helped by a passer-by, chased the robbers and retrieved his stolen belongings.

Det Con Steve Martin, said: “Fortunately the man wasn’t injured and managed to get his belongings back but I am still keen to catch whoever is responsible.

“The man and woman were last seen going into Agnes Court and I would like to appeal to anyone who may have witnessed the offence to get in touch.”

Police said the woman was aged between 16- and 20-years-old, white and about 5ft 3in.

She had dark hair, dyed blonde at the side and back, and was wearing hooped silver earrings, a dark jumper and dark trousers.

The man was of a similar age, white, medium build and had short, mousey-coloured hair.

He was around 6ft 2in and was wearing a hooded top, dark trousers and dark trainers.
