Around 30,000 suspects have been arrested in China's capital here and 17 million illegal online messages deleted during a 3 year crackdown on cyber crime.
The three-year campaign that began in 2011 has resulted in the detention of over 50 suspects implicated in terrorism related activities besides deleting about 17 million illegal online messages, Beijing's public security bureau said.
The clamp-down targeted cyber crimes, hackers, online rumour-mongering as well as terrorism and violent content, latest data released by the bureau said.
Penalties were also stepped-up for violating Internet laws and regulations by the police.
In 2011, around 1,000 operators were punished in accordance with the law and the number soared to 11,000 two years later.
Official data showed that by the end of last year, Beijing was home to more than 900,000 licensed websites, with about 70 per cent of China's major web portals located in the capital city, and an online population exceeding 16 million, the report said.
