THREE people have been arrested in connection with a fatal collision in Royston.

The crash in Melbourn Street, in which a man was killed and another injured, happened at just after 1am this morning, closing the road and the junction with the A10.

Two teenagers from Buntingford, aged 17 and 18, and a 17-year-old from Hertford have been arrested and questioned.

Hertfordshire Police will not comment on the crash and have referred the matter to the Independent Police Complaints Commission - who are investigating the incident.

“At this early stage it is understood that at around 1am officers signalled for the car to pull over, which it did not do, and that a short time later the car overturned on Melbourn Street,” a spokesman said.

“The IPCC deployed investigators to begin collecting evidence and following an assessment it has been decided that an independent investigation will be conducted,”

Details are unclear at present but it is believed a car overturned and collided with a set of traffic lights.

Hertfordshire Fire and Rescue Service and The East of England Ambulance Service also attended the scene.

Gary Sanderson, ambulance service spokesman, said: “We were alerted to a report of a road collision in Royston at 1.10am this morning (Monday, June 20).”

“Ambulance crews from Letchworth, Royston and Stevenage attended the scene.

“Two patients were injured and were taken to Addenbrookes in Cambridge and the Lister Hospital in Stevenage.”
