A Vietnamese woman was detained by police for smuggling more than 1,000 grams of heroin into China, according to a police source in southwest China's Guangxi Zhuang Autonomous Region on Saturday.
The woman, whose name on her passport is Trinh Thi-hien, 32, was seized at a check point at the China-Vietnam border. Police discovered 1,045 grams of high-purity heroin concealed in a hard-bound book cover.
Police said the woman has confessed that she smuggled the drug to help her boyfriend to pay off a gambling debt.
The woman's passport showed she had made frequent entries into China before the arrest, but she said it was her first attempt to smuggle drugs.
She said she got the drug embedded in the book from a dealer in Vietnam on April 9, who told her to send it to Pingxiang City in Guangxi after entering China via the checkpoint.
Police did not disclose further details on the development of the case, but said it was a big seizure in drug trafficking.
