Thirty people in the US state of Texas were on Friday charged with conspiracy to distribute and possess Mexican-produced methamphetamine.

According to local TV channel ABC13, US Attorney John Malcolm Bales announced on Friday the indictment in Plano, Texas.

He said that the people indicted were believed to have distributed more than 225 kg of methamphetamine, which, also known as metamfetamine, is a psychostimulant of the phenethylamine and amphetamine class of psychoactive drugs.

These people were reportedly part of a network that sold methamphetamine in Greenville, about 80 km northeast of Dallas.

Three of these people are still on the run, and authorities have called for help to bring them to justice.
