ZHENGZHOU, March 22 (Xinhua) -- Police in central China's Henan Province have seized 107 suspects in connection to a telecom fraud case.

Police in Xinyang City said Thursday the case involved more than 20 million yuan (about 3.2 million U.S. dollars), and six dens were broken up.

Last August, police found that a company promoted online gambling through WeChat, a popular instant messaging tool. They then started investigating the company.

After six months of investigation, another five companies were also discovered to be involved in online gambling.
