A teenager is believed to have been attacked with a piece of wood outside a busy shop.

The 15-year-old was set upon by up to five youths outside the Spar shop in Dunnock Way, Greater Leys in Oxford.

The assault happened at around 6.45pm on Sunday December 16 but police only released an appeal for witnesses today.

Police investigating the incident said the attack happened minutes after a report of a burglary in Appletree Close, Greater Leys.

Pc Robert France, of Oxford Burglary Team, said: "The boy was followed from his home and set upon.

"We think there could be up to five people involved in the assault.

"There is also a concern that a weapon, possibly a piece of wood, was used during this incident.

"The victim has not been able to identify his attackers, so we are hoping local people can help us.

"It was a busy time near a popular local shop and I am sure someone must have seen something.

"If anyone has any information that might help us better understand what happened that night please get in touch."

Anyone with information should contact police on 08458 505505 or speak anonymously to Crimestoppers on 0800 555 111.

* A 16-year-old girl has been arrested in relation to the incident and released on police bail until 21 January.
