“We continue to seize these large amounts of drugs, and what we want our constituents to know and the good citizens of Tarrant County to know [is that] this is a clear and present danger to us until we continue this fight,” said Tarrant County Sheriff Bill Waybourn. “But we also want to send a clear signal to the bad guys that we are standing shoulder-to-shoulder in this fight and we will continue to do that.”

While officials would not confirm how many people were arrested, they did say they believe the narcotics are from a cartel.

Teams from the Tarrant County Sheriff’s Office, Drug Enforcement Administration (DEA), Texas Department of Public Safety (DPS), and Dallas, Fort Worth, Mansfield and River Oaks police departments were a part of the joint operation.
