A Chinese teenager sent to an internet addiction rehabilitation camp has allegedly been beaten to death by its counsellors, according to reports.
A number of employees of the Qihang Salvation Training Camp in Nanning have been arrested over the death, his father Deng Fei told the Global Times.
The camp had promised to put Deng Senshan, 15, under 24-hour supervision.
China is increasingly taking action against what it sees as a pandemic of web addiction.
Some estimates suggest up to 10% of the country's 100 million teenage web users could be addicted, and a growing number of rehabilitation services exist.
However, there is little consensus on how to treat the addiction. In July, China's Ministry of Health formally banned the use of electroshock therapy as a treatment option.
According to the China Daily newspaper, an agreement the teenagers' parents signed with the camp said: "The centre can take necessary approaches including punishment to educate the teenager, as long as the approaches will not abuse the child or impair his health."
Camp staff are alleged to have put the teenager in solitary confinement on Saturday and then beaten him that evening.
