A motorist has been convicted of dangerous driving after he was caught using blue lights and sirens 38 times to avoid traffic.
Martin Chapman was filmed by cameras while dodging traffic in his Vauxhall Astra in Northampton.
In one clip recorded by CCTV cameras at a set of traffic lights, the 35-year-old drove on the wrong side of the road to overtake stationary cars and narrowly avoided hitting a bicycle.
The incident happened on July 6 on Cliftonville Road and was described by the arresting officer as a "dangerous and reckless manoeuvre".
After his arrest Chapman, of Connaught Street, The Mounts, Northampton told police he had joined the blood service and had intended to use the lights and siren "to do urgent blood runs between hospitals". However, he later admitted that he did not have a contract for such work.
He was found guilty of one count of dangerous driving, three counts of ignoring a red light and road markings and five charges of using a car without correct insurance. He admitted five charges of using a vehicle fitted with a blue warning beacon without permission.
Bench chairwoman Jackie Shore said that because the dangerous driving offence was "so severe," Chapman would be sentenced at Northampton Crown Court on February 10. He has been given a temporary driving disqualification until then.
