An investigation continued Thursday into the arrests of about 75 undocumented migrants in connection to an alleged large-scale illegal marijuana operation in Thermal.
The Drug Enforcement Administration Los Angeles Division said it led a multi-agency effort to seize more than 700 acres of marijuana on Wednesday.


“Due to the magnitude and topography of this operation, DEA has requested support from multiple federal partners,” according to a DEA statement on X.
Participating federal partners included the National Guard, FBI Los Angeles Division and Immigration and Customs Enforcement, according to the DEA.
The agency said search warrants were authorized by a federal magistrate judge.
