UPDATE: Driver crashes after having 'medical episode'

Police are attending an incident near the Churcill Hospital in Headington.

A twitter update from Oxfordshire County Council's traffic feed said there are currently delays around the Oxford hospital.

It added Old Road was restricted 'whilst police attend an incident' and people should expect delays in the area and seek other routes where possible.

Oxford Bus Company also tweeted its City15 service was unable to acces Churchill Drive and Roosevelt Drive due to an 'ongoing police incident' at the hospital's entrance.

Live traffic feeds show Old Road is blocked. 

Thames Valley Police has been contacted.
