A father is offering £15,000 of his pension as a reward for information about his son's killer.
Mumtaz Khan, 70, who is seriously ill, has put up the five-figure sum in the hope that it will lead to finding Junaid Khan's killer, as he prepares to mourn the 10th anniversary of his death.
In addition to the money being offered by Junaid's father, a further £50,000 is being offered by police for information.
Junaid, 21, was shot dead in the car park of a doctors' surgery in Chadderton, Greater Manchester, on July 9, 2009.
The killer was using a Mach-10 machine gun. Four men went on trial for his murder in June 2011, but all were cleared by a jury.
Initially a fifth suspect was wanted in connection with the case.
He is believed to be in Pakistan, but Crown lawyers later advised police there was no case to pursue in relation to him.
"My health is deteriorating. I have multiple health problems and I want justice before I die.
At Manchester Crown Court the prosecution alleged the killing was the climax of a 'long-standing' feud.
Detective Chief Inspector James Faulkner, of Greater Manchester Police, said: “In the lead up to the 10 anniversary of Junaid Khan’s death, I would like to take this opportunity to stress just how committed Greater Manchester Police remain to seeking justice for his ruthless and brutal murder.
“We’re still striving to provide Junaid’s family with the answers they deserve and a decade on, we’re continuing to appeal for the public’s help to trace those responsible.
“I am confident that someone, somewhere holds vital information about Junaid’s death and any new information will be assessed and treated incredibly seriously.
“Please, help us give Junaid’s family the justice they deserve."
Anyone with information about Junaid’s murder should contact police on 0161 856 8972, via 101 or via the independent charity Crimestoppers, anonymously, on 0800 555 111.”
