NEW evidence has cast fresh doubt on the conviction of two men jailed for the notorious gangland killing that inspired the Michael Caine thriller, Get Carter.

The Northern Echo has been given exclusive access to documents submitted to the Criminal Cases Review Commission (CCRC) which claim Michael Luvaglio and Dennis Stafford were the victims of a miscarriage of justice after a botched investigation by Durham Constabulary.

The two men have always denied murdering gaming machine collector Angus Sibbet, whose bullet-ridden body was found in his Jaguar under Pesspool Bridge, South Hetton, County Durham, 47 years ago on January 5, 1967.

As part of their two-year investigation, former Echo photographer Ian Wright and documentary film maker Neil Jackson spoke to a witness who claims he met a man in a Darlington garage who confessed to the killing hours after the murder.

The witness has worked with a former police artist to produce a sketch of the suspect.

Although the claim was included in a statement to police ahead of an appeal by Luvaglio and Stafford in 1972, however is understood the evidence was never disclosed to the defence teams and the appeal failed.
