TOKYO - TOKYO police said on Monday they busted a child pornography ring alleged to have made more than a million dollars running a 'factory' producing obscene DVDs.

Officers arrested Jun Amaya and six other men suspected of selling 'a DVD depicting sexual scenes of children', a police spokesman said.

They were arrested in a Tokyo building on November 26 but police are continuing investigations amid suspicions of further wrongdoing, the official said.

Jiji Press news agency said the men had run 'a manufacturing factory' of child porn DVDs on a floor of the building equipped with 26 computers and 19 DVD copying machines.

They racked up profits of 110 million yen (S$1.77 million) selling some 300,000 DVDs through their websites since July last year, Jiji said.

They made the DVDs with images lifted from the Internet and copied them from 8am to 5pm daily, with Amaya giving a monthly salary of 250,000 yen (US$2,700) to each of the six other men, Jiji said.

Police have confiscated three truck loads of machines, DVDs and other items, the private Asahi television network said.

Japan is considered a major provider of child pornography and the United States and other developed countries have accused it of laxness in dealing with the problem. -- AFP
