More Than 20 Mexican Mafia Gang Members Arrested in Historic Raids

"Not in my town." That's the message Seguin police hope they got across to gangs.

Nearly a dozen raids were executed as the result of an 18-month long investigation into the Mexican Mafia.

Seguin police say that, as a result, they've put a dent in the gang and drug activity in their community.

Among the day's take: piles of drugs, $60,000 in cash, and several weapons removed from nearly a dozen locations where Mexican Mafia gang members were known to operate. "We do believe that this is going to cause an incredibly serious interruption in the Mexican Mafia in this region," Seguin Police Department Deputy Chief Bruce Ure said.

The investigation into the drug activity began in Seguin 18 months ago with other local, state and federal agencies helping with the execution of those search warrants. "The operation spanned as far west as San Antonio and went as far east as the Houston area. And as far north as New Braunfels," Deputy Chief Ure said.

All the arrests resulted in federal and state drug charges.

One woman at the scene says her family has no affiliation with the Mexican Mafia. "There's no gang members here. They need to get their investigation straight before they come accusing," said Amy Herrera, whose family's home was raided. But police say that all of the locations raided Friday were known to have drug activity. "They are all known Mexican Mafia gang members and if you know anything about the Mexican Mafia, they're a vicious, vicious gang," Deputy Chief Ure said.

It's a gang they hope they have sent a strong message to. "Our gang members need to know whether you're in the MS13, or the Mexican Mafia, or where ever you are. If you're in our region, you're on our radar," Deputy Chief Ure said.

Those that were arrested remain behind bars, including a high-ranking "lieutenant," until their detention hearings in federal court.

Authorities say they are still searching for three other men wanted for drug charges.
