An initial appearance is scheduled for Friday morning in Lubbock federal court as part of a large-scale narcotics and cash smuggling investigation involving 21 defendants.

The scheduled initial appearance comes after a multi-agency raid involving the federal Drug Enforcement Agency was conducted Thursday morning in Lubbock and Terry County.

Agents from the federal Drug Enforcement Agency coordinated with Brownfield Police and Texas Department of Public Safety troopers to raid multiple locations in Lubbock three locations in Terry County, including a residence and business - Wholesale Tire Co. - in Brownfield and another location in Meadow, according to the Brownfield News.

Officials were not immediately available to provide additional information, but court documents obtained Thursday by the A-J indicate 21 people have been indicted by a federal grand jury in connection with an array of federal charges ranging from conspiracy to distribute and possess with intent to distribute controlled substances - including cocaine, methamphetamine and marijuana - and bulk cash smuggling.

Although their indictments were sealed as of Thursday, some documents released Thursday indicated several of the defendants are already in custody and some are foreign nationals.
