Fifty people, including inmates, will face trial at a court in Phu Tho Province, charged with trafficking narcotics into a local prison, prosecutors said Wednesday.
The ring had sold drugs worth billions of dong (with VND1 billion equal to US$47,060 at present) to inmates of Tan Lap prison for more than a year before it was discovered in early 2013, prosecutors at the People's Procuracy of the northern province said.
The investigation began after prison security officers caught Ha Kim Doai, who is serving a life sentence for drug trafficking, hiding 25 small bags of heroin in her bucket when she returned to her cell from an outdoor labor session in January 2013.
Police found 51 suspects involved in the ring, including inmates, ex-inmates and local drug dealers. One of them died last year of AIDS.
According to the indictment, after receiving orders from inmates in Tan Lap prison, the suppliers would bought drugs and hide them in places around the prison where social works sessions are often organized.
Inmate members would pick them up when they attended those sessions and deliver to buyers. Payments were transfered through banks
Among the indicted, one had been convicted of drug trafficking and had his death sentence commuted to life term just recently, local media said.
Tan Lap prison was managed by the Criminal Case Enforcement and Justice Assistance Department at the Ministry of Public Security.
