The family of an alleged kidnap victim whose severed thumb was found in a street have offered a £10,000 reward for information to help find his body, police said today.
Mahmood Ahmad, 41, is believed to have been abducted from outside his family home in Watford in the early hours of March 7.
His severed thumb was found in Ilford, north east London, by a member of the public on March 10.
His body has not yet been found but five people have been charged with his murder.
Hertfordshire Police said Mr Ahmad's family has put up a £10,000 reward in the hope that someone will come forward with information to help locate his body.
His wife, Farah Ahmad, 37, said: "The past few months have been a living nightmare for all of us and we are so desperate for information about Mahmood.
"Not knowing what has happened to him is extremely difficult to deal with.
"We are facing a daily battle to try and come to terms with everything and I would like to make a plea to anyone who has any information which can help the police and bring us some closure to call police or Crimestoppers.
"We realise that it may be difficult for you to pass on the details but I would urge you to think about what myself and the family are going through."
Detective Chief Inspector Melanie Burn, from the Bedfordshire and Hertfordshire Major Crime Unit, who is leading the inquiry, said: "As you can imagine, Mahmood's family are desperate for answers about what has happened to him.
"They are being supported by specialist family liaison officers and my team are continuing extensive inquiries in relation to the investigation.
"However, I would once again appeal to anyone with information about Mahmood's whereabouts to contact us without delay."
