The father of a Bradford man, serving a 35-year jail sentence for his role in the gang torture and murder of Bradford car dealer Teddy Simpson, says he has evidence to prove his son’s innocence.

Patrick Davies said the evidence “could, should and probably would” take his son Anthony’s case back to the Court of Appeal.

Mr Davies was speaking after a BBC Panorama investigation into supergrasses highlighted the murder of Mr Simpson, who was beaten and abducted from his home in Sticker Lane, Laisterdyke, in August 2007, during a botched robbery.

The great-grandad’s semi-naked body was dumped in the grounds of a disused nursing home in Wyke.

Anthony Davies, then of Lloyds Drive, Low Moor, was one of five men jailed for life for Mr Simpson’s murder. He was said to have recruited the three men who went into the victim’s house to commit the robbery.

Two other men were given jail terms after they were convicted of conspiracy to rob. The gang had hoped for a money and drugs haul in excess of £250,000.

Former Bradford man Sonny Stewart, the “supergrass” whose evidence helped to convict the rest of the gang, was jailed for seven years after entering into an agreement with the prosecution and pleading guilty to manslaughter and conspiracy to rob. He has since been released.

But Davies’s barrister, Benjamin Nolan QC, told Panorama it had been a bogus charge created for Sonny Stewart, who had “slipped up” during the police interview.

Davies, now 31, along with three other gang members, lost an appeal against conviction two years ago.

But Patrick Davies, who featured on the Panorama programme, told the Telegraph & Argus yesterday: “It will help my son’s case because it shows that he wasn’t involved and there was no evidence against him other than by the supergrass. You have to question the reliability of his evidence.”

Mr Davis claimed Sonny Stewart had used the police and the system for his own benefit.

The Criminal Cases Review Commission is investigating the case of Anthony Davies, and that of one of the “hitmen,” Errol Witter, and Mr Davis said he would await the outcome of that and then take stock.
