His parents hoped their teenage son would be home in a month, cured of his addiction to the internet. They never thought that within 10 hours of taking him to an addiction clinic they would receive a telephone call notifying them that he was dead.
Deng Senshan, 16, was addicted to playing on the internet, like tens of millions of other young Chinese. He was the latest teenager to be sent by his parents to one of the clinics being set up across China to cure youngsters of their obsession with online gaming.
His parents took their son to the Guangxi Qihuang Survival Training Camp in southern China on Saturday.
Deng Fei, his father, told supervisors that his son was shy and introverted and they should avoid putting too much pressure on him during the first couple of days.
Instead, the boy was placed in solitary confinement shortly after his arrival and then beaten by his trainers who scolded him for running too slowly when he was ordered to go jogging.
He was pronounced dead in the early hours of Sunday morning.
"My son was very healthy and was not a criminal," his father said. "He just had an internet addiction when I left him at the camp. We can't believe our only son was beaten to death."
