Police have busted an armed trafficking ring in the northeastern Chinese province of Jilin, arresting 89 suspects as part of a campaign to clamp down on illegal drugs.

Police nabbed the ring's leader, whose pseudonym is Liang Si, and his subordinates after they traced the ring's activities across the country from northern Heilongjiang Province to Sichuan Province in southwestern China.

Nearly 2 kilograms of crystal methamphetamine, commonly known as "ice," were seized during the police raid, said officials with the provincial public security department. Two handguns, eight vehicles and 400,000 yuan (about 61,538 U.S. dollars) were also confiscated.

Officials declined to disclose the details of the case, saying the investigation is still underway.

Jilin started a three-month campaign to crack down on drug-related crimes on May 1. Police have arrested 329 suspects, some of whom were allegedly involved in smuggling illegal drugs across China's border. More than 126 kilograms of illegal drugs have been seized so far.
