LOS ANGELES (KTLA) -- Close to 100 people were arrested during during a series of raids Wednesday for alleged ties to Mexican Mafia prison gangs.

In an action deemed "Operation Black Flag," local and federal law enforcement authorities raided 42 locations in Orange County, Los Angeles County and Riverside County.

The raids targeted 90 people who have been named in federal indictments.

The suspects arrested range from street soldiers to the upper echelon of the Mexican Mafia, according to police.

Authorities say the arrests are a major blow to the gang.

"We are delivering a powerful message to the Mexican Mafia and those gangs associated with the Mexican Mafia... for them to understand in no uncertain terms that their criminal acts will be met with the most severe consequences," U.S. Attorney Andre Birotte said.

"We stand here this morning united in one message," Birotte said. "No gang member, none at all, is untouchable."

"Working together, we intend to dismantle both street gangs and prison gangs."

Wednesday's arrests marked the end of a 32-month-long investigation.

It involved several different government organization and law enforcement working together to get gang leaders off the streets.
