ZHENGZHOU - 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), 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.
