China's state media says more than 1,000 people have been arrested since mid-February in an intense, nation-wide crackdown on what have been called Internet-related crimes.  March that six people had been arrested in a campaign against the spreading of supposedly harmful online rumors, which was linked to widespread speculation about political unrest in China. But in a new report this week, Xinhua says 1,065 suspects have now been arrested. It also said 16 websites have been shut down and more than 208,000 harmful online messages deleted. The report said the crackdown was necessary to ensure social stability, specifically mentioning online rumors that spread in March of a possible coup.
