In a nationwide crackdown on online prostitution, gambling and arms deals, Chinese police have detained more than 5,100 people, the Ministry of Public Security (MPS) announced on Wednesday.
The MPS said police across the nation cracked about 1,980 cases and busted over 120 gangs since the campaign was launched in March, Xinhua reported.
The illegal activities include cross-border gambling websites run by overseas casinos, organised prostitution through instant messaging services, and selling guns and explosives online.
The MPS vowed to continue combating such activities by paralysing hosting for illegal websites.
