A man who allegedly stabbed a 66-year-old good Samaritan to death on Saturday afternoon was on day release from Springhill Prison in Grendon Underwood.
It has emerged that Ian John McLoughlin was 22 years into a life sentence for the murder of a Brighton man when he was let out on day release from the Vale prison.
McLoughlin had also previously served eight years behind bars for the manslaughter of another man in October 1983.
It is understood that the 55 year old had arranged to visit old Etonian Francis Cory-Wright in Little Gaddesden, near Tring, on Saturday after they had met while in prison.
The 86 year old recently served a prison sentence for abusing a 10-year-old boy during fishing and shooting trips in the late 1970s.
It is believed that McLoughlin was at Cory-Wright’s home for some time before the violence erupted.
The alarm was raised when neighbour Graham Buck, 66, who lived two doors down in Nettleden Road, heard Cory-Wright’s cries for help.
When he went to his aid, Mr Buck was stabbed to death before McLoughlin fled in a taxi heading towards Watford.
Police have since had a report of a sighting in nearby Bedmond on Sunday afternoon at around 2.30pm.
Forces across the country have now been informed of the manhunt for McLoughlin and border agencies are on the lookout to prevent him from leaving the country.
He is described as ‘very dangerous’ and the police are urging members of the public not to approach him but to instead dial 999 if he is spotted.
Cory-Wright, who suffered minor injuries in the attack, has since been released from hospital.
