CHANGSHA, Dec. 16 -- Police in central China's Hunan Province have busted a cross-border drug trafficking gang, capturing 3 suspects and confiscating about 2.12 kg of heroin and 571 "magu" pills, a stimulant composed of methamphetamine and caffeine, according to police.

Customs in Changsha, capital city of Hunan Province, and police in Chenzhou City published a statement about the case on Monday.

According to the statement, in November, Changsha Customs intercepted a parcel filled with heroin that was mailed from the China-Myanmar border trade zone in the southwest city of Ruili to Guiyang County in Chenzhou City.

After a 10-day investigation, the parcel was sent to Guiyang County as planned to lure the gang members, the statement said.

Two suspects were caught while collecting the parcel, and the gang leader, surnamed Zhang, was arrested in a hotel shortly afterward.
