Knifeman jailed for police attacks
A knifeman described as one of the most dangerous men in Britain has been jailed for life for trying to kill two police officers after a row about a bus ticket.
John Onyenaychi, 30, cut Pc Paul Madden's throat as people watched in horror, he then lashed out with his knife at other officers who tried to restrain him, the Old Bailey heard.
Pc Madden's life was only saved by the quick thinking of a retired heart surgeon who was out Christmas shopping.
Samad Tadjkarimi, 65, also helped Community Support Officer Piotr Dolata, who was also stabbed by Onyenaychi in Ealing, west London, last December.
Pc Madden, 23, was taken to hospital by helicopter and received emergency surgery for injuries to his neck, throat and face. He was left with permanent scarring. PCSO Dolata, 27, needed 12 stitches to his head.
Fellow PCSO Steven Constable was slashed twice but escaped serious injury because his high-visibility jacket saved him.
The attack on the three officers was the culmination of a five-day violent crime spree.
Onyenaychi, 6ft 2in, refused to come out of his cell during the nine-day trial and the Recorder of London, Judge Peter Beaumont, said Onyenaychi had not shown any remorse.
Onyenaychi, of Wise Road, Stratford, east London, was found guilty of two counts of attempted murder, causing grievous bodily harm with intent, robbery and attempting to cause grievous bodily harm.
He was ordered to serve a minimum of 25 years for the attack on Pc Madden, and given a second life term with a concurrent minimum of 20 years for attempting to murder PCSO Dolata.
