A 26-year-old who killed a man has been sent back to prison to complete his sentence after being caught driving while disqualified. In May, last year, Jack Mulcahy was jailed at the Old Bailey for four years and three months after being convicted of causing death by dangerous driving. Alex Jeffery, 21, died after he was struck by a car being driven by Mulcahy, of Capulet Court, Huntingdon. The incident followed an argument between two groups, in Cambridge, in November 2014. Mulcahy, who also received a five year driving ban and ordered to sit an extended retest, was released after serving half his prison sentence. On Monday, May 22, he was stopped by police driving his girlfriends car and was arrested for driving while disqualified. He was remanded into custody and placed before the next available court. He appeared at Peterborough Magistrates Court on Tuesday, May 23, and was sentenced to 18 weeks. Mulcahys license was also revoked. PC James Thorne said: In 2014 Mulcahy caused the death of Alex Jeffrey, who was out enjoying himself, by running him over. He was disqualified following a trial and to discover that he has been driving is completely unacceptable. I am delighted to see that he will serve the remainder of his sentence in prison where he will no longer pose a danger to the public.
