The parents of a backpacker who disappeared in Cambodia three years ago have offered a £10,000 reward for information about his whereabouts.
Jo and Mike Gibson appeal on Cambodian TV for information
Eddie Gibson, from Hove, was a student at Leeds University when he vanished while travelling in South East Asia.
His parents, Mike and Jo, made a TV appeal in Cambodia on Tuesday.
"There is nothing worse in life than losing a son, but not to know what happened to him is even worse," said Mrs Gibson.
Eddie, then 19, was three weeks into a combined Asian and Pacific studies and international management course when he travelled to the Far East.
An e-mail to his mother on 24 October said he was planning to return home on 1 November. But when the family went to meet him off a flight from Thailand, he was not on it.
Eddie's movements remain a mystery after 23 October 2004
"Eddie is a loving and caring son," said Mr Gibson in the Cambodian capital Phnom Penh.
"Because we have not heard from him since October 2004, we fear he may not be alive but we still have hopes that our son can be found safe."
Mr Gibson has made five previous trips to Cambodia to search for his son and four Sussex Police officers spent 10 days in Phnom Penh last summer.
Investigators have completed a picture of Eddie's movements up to 23 October, but Mr Gibson said they wanted to hear from anyone who saw him on the following day.
