A car-jacker who lured a Bradford father to his death for the sake of a £10 watch has been jailed for eight years.

Jermaine Raphael, 21, organised the robbery of Mohammed Ashraf, who had agreed to sell him a Nissan Primera for £700.

He believed Mr Ashraf's watch was valuable but it turned out to be a fake.

Nathan Johnson, 20, and Nyrah Hales, 17, battered Mr Ashraf with a crowbar and stabbed him 18 times, leaving him slumped over the wheel of his car in Plaistow, east London.

Hayles later acted out how he stabbed the victim to death and boasted to a girlfriend: Did you see me do this?' Raphael organised a second robbery and had also pulled a gun on staff at McDonalds - because his friend did not have enough chocolate sauce on his McMuffin.

Mr Ashraf, who had a one-year-old daughter, may have been targeted after Raphael began supplying him with cannabis.

The 35-year-old had recently been forced out of work by a car accident and had borrowed his father's Nissan Primera after a trip to see his family in Reginald Street, Marshfields, Bradford.

On September 22, 2005, he left his home at around 11pm after telling his wife he had sold the car for £700.

"He arranged to drive to a quiet back street off the Barking Road, Plaistow, where he believed he was going to meet someone who would buy his car," said prosecutor Anthony Leonard QC.

"His contacts for this were Jermaine Raphael and Nathan Johnson. By 11.30pm residents and visitors in that street heard his car horn sounding."

Mr Ashraf, who lived with his wife and daughter in Frinton Road, East Ham, was taken to hospital but was pronounced dead at 12.25am.

The Old Bailey heard how Hayles demonstrated how he would stab Mr Ashraf to a girlfriend hours before the robbery.

After the attack he went back to the girlfriend's home in bloodstained clothes and told her: I stabbed someone.' Johnson and Hayles had also snatched a car from Gbemi Adeosun, 18, a month before the murder.

Judge Anthony Morris told Raphael: I am satisfied you organised the robbery of both the victims in this case.

"Although you were not party to the murder and were not indicated with it you were responsible for recruiting people like Hayles and Johnson, who you knew to be capable of extreme violence."

Johnson, known as Tubbs', of Sutton Road, Plaistow, and the Hayles, of Luke House Hotel, Limehouse, were both convicted of murder and jailed for life with a recommendation they serve 17 years each.

Johnson and Raphael, of Brading Crescent, Leytonstone, east London were also convicted of two charges of conspiracy to rob.

Raphael admitted one charge of possessing an imitation firearm.
