In a sweeping, pre-dawn raid in Los Angeles on Tuesday, twelve wanted criminals were arrested in a dramatic seven-agency sting led by the Department of Homeland Security.

The bust was the culmination of a nearly two-year investigation dubbed “Operation Supper’s Ready,” that targeted dueling transnational gangs that U.S. officials say are exploiting and terrorizing the United States.    

The competing gangs are accused of terrorizing their American neighborhoods, shooting at each other and in one instance kidnapping and torturing another member, capturing the violence on video.

The tension between the two was evident at the command center on Tuesday where they were being collectively gathered and processed. At point there, while two of the men were handcuffed and chained at the feet, one of them slammed his body into another, leading to a shouting match and law enforcement separating the two.

“This is purely an operation that makes the community much safer,” said  HSI Los Angeles Acting Deputy Special Agent in Charge Dwayne Angebrandt.

DHS and the U.S. Attorney in Los Angeles told Fox on site that the ability to make arrests at home and carry out these types of stings has become much easier under the Trump administration.

“We’ve been able to go after these criminals much more robustly and able to attack them where they live,” Angebrandt said.

The U.S. Attorney’s Office says approximately $100,000 in cash, three armored vehicles, and 14 firearms were recovered during the bust and one suspect remains at large.

If convicted, the defendants could face between 10 years and life in federal prison, as well as deportation.

“It’s a privilege to be here on a visa or other temporary status within our country. So they are visitors, they violate our laws, and they’ll be prosecuted, hopefully convicted, and then removed,” said Essayli.

Law enforcement tells Fox the sting got its name “Operation Supper’s Ready” based off a picture depicting some of the suspects enjoying a “mob-style” dinner.
