PICTURES of an Oxford man seriously hurt in a hit and run incident have been released by police in a fresh appeal for witnesses.

Steven Wanna is thought to have been hit by a vehicle in Nuneham Courtenay just after midnight on Valentine's Day.

The 20-year-old is being treated in hospital for 'extremely serious' injuries after being found on the A4074 and may not recover fully, Thames Valley Police said. 

Speaking on behalf of Mr Wanna's family, his uncle Charlie Koko said: “We just want to find out what happened to Steven that night and we want someone to come forward with any information which will help us.”

Police said the road was closed between the Goldenballs and Berinsfield roundabouts on February 14 and while officers investigated the scene.

Investigating officer PC Victoria Jones, based at the Serious Collision Investigation Unit in Reading, said: “As you see from the pictures, Steven is in an extremely serious condition and may never make a full recovery from his injuries.

"We are appealing for anyone who was in the area at the time and who may have noticed anything unusual in the road to contact us as a matter of urgency on 101 quoting URN 12 14/2.”
