HANGZHOU, Sept. 6 (Xinhua) -- Police in east China's Zhejiang Province arrested 63 people for organizing online football gambling involving around three billion yuan (438 million U.S. dollars).

Police in the city of Ningbo received a tip-off about a gang setting up online casino in April. An initial investigation showed that the gang was led by a man surnamed Dai and run by different levels of agents who deduct different percentages from the gambling money brought to the website.

In July, the police launched a raid and apprehended 38 suspects. So far, police have captured 63 suspects, with around 10 still at large.

Police have also confiscated 2.25 million yuan of illegal income and frozen 5 million yuan in their bank accounts. The total illegal income reached more than 30 million yuan, police estimated.

The case is under further investigation.
