Experts have urged police nationwide to give officers more training and better equipment to combat the growing threat of online crime, as Beijing released the results of its six-month computer crime crackdown.

The capital's public security bureau said more than 4,000 cases of Internet crime were investigated between January and June this year.

During the campaign the authority removed roughly 360,000 pieces of illegal information from the Web including those from sites promoting pyramid schemes, pornography and gambling, and detained more than 5,000 suspects.
