Seven record firms, including Universal Music and Warner Music Hong Kong, are suing an unemployed single father of four for illegally sharing music on the internet, even though he claims he does not know how to switch on his computer.

The record firms want an injunction to stop Yeung Chun-choi, 54, of Hong Kong, "infringing their copyright". Yeung, a former builder, suspects that his two daughters are the culprits, according to the South China Morning Post. He said that the teenagers used the computer, which was supplied by a social worker, to do their homework.
