NANJING, Feb. 26 (Xinhua) -- Police in east China's Jiangsu Province have busted a drug trafficking gang, in which four minors were involved in smuggling drugs in their bodies.

Eight suspects, including the gang leader surnamed Lu, have been arrested since police spotted a man on the train teaching a teenager over the phone how to excrete drugs from his body in September 2018, railway police in Nanjing, capital of Jiangsu Province, said on Monday.

A total of 1.27 kg of heroin was seized.

The final suspect of the gang surnamed Gao, who lured four teenagers into drug dealing, was arrested on Feb. 17, according to police.

The boys, aged between 16 and 17, dropped out of junior high school from a remote area of Yunnan Province in southwest China. They were lured to the China-Myanmar border with "well-paid jobs" and they were confined for a month until they agreed to carry drugs.

The boys were asked to swallow drugs wrapped in plastic capsules and take motorcycles to Yunnan's Xishuangbanna before delivering them across the country by plane.

Each of them, who carried 300 grams of drugs each time, was paid 10,000 yuan (about 1,500 U.S. dollars) per trip.
