A British man who was arrested in 2013 for conspiring to bring 100 kilograms of pure North Korean meth into the U.S. in 2013 has pleaded guilty to the charges against him.

Scott Stammers, 46, was among five people arrested in Thailand in September of 2013 after authorities discovered they'd been storing the drug with the intention of distributing it in the U.S.

Tan Lim, a member of a crime ring who had been working with Stammers, said in Manhattan court that the North Korean government had destroyed many of the country's meth labs, though not those belonging to his organization. He said that the group stockpiled one ton of North Korean meth in the Philippines, and that the plan was to deliver 100 kilograms of drugs to the U.S. from Thailand. Stammers's job was to arrange for the meth to be counted, repackaged and delivered to a marina in Thailand, to be transferred to a boat that would deliver the drugs here. He was arrested on September 25, 2013.

The meth was seized by the government and tested as being 99 percent pure. (That's tight. Tight tight, yeah.)

Stammers faces 10 years to life in prison. Another man, 32-year-old Philip Shackels, will be tried in New York in September.

“Scott Stammers conspired to import into the United States 100 kilograms of dangerously pure North Korean methamphetamine," Manhattan U.S. Attorney Preet Bharara said in a statement. "Thanks to the work of the DEA and the cooperation of law enforcement partners around the world, including in Thailand, Liberia and Romania, Stammers’s scheme ended, not with the North Korean methamphetamine flooding American streets as he had intended, but rather with a guilty plea in a Manhattan federal court.”
