A £1,000 reward has been offered to try to trace a man police want to question over the death of a pedestrian in a car crash in Hertfordshire.
Ricky Burlton, 20, from Enfield, died in the crash early on 4 June on the A10 exit slip road at Hoddesdon.
Police believe Georgios Tsoulos, of Woodlands Road, Hertford, was driving the car involved in the incident.
He is wanted for questioning on suspicion of causing death while driving a vehicle.
He is also wanted on suspicion of driving while being an uninsured and unlicensed driver.
On the day of the collision, Mr Tsoulos was transferred from North Middlesex Hospital to Chase Farm Hospital in Enfield where he was treated for injuries to his face.
He was due to be transferred to Moorfields Hospital in London for further treatment to an eye injury but has not been seen since.
Mr Tsoulos is believed to be Albanian and living in the UK under a false Greek identity.
Last month, police issued new images of Mr Tsoulos.
The £1,000 reward has been put forward by Crimestoppers and police have urged anyone who knows of his whereabouts to contact police or Crimestoppers.
