MANASSAS, Va. — The alleged leader of the violent MS-13 street gang on the East Coast has been arrested in Virginia, U.S. Attorney General Pam Bondi announced Thursday.

Bondi lauded the the early morning arrest of the 24-year-old man from El Salvador, who was described as one of MS-13’s top three leaders in the United States, as a major victory in the Trump administration’s effort to crack down on a gang known for brutal violence and extortion.

Arrest Details and Charges

Henrry Josue Villatoro Santos was taken into custody in northern Virginia on an outstanding administrative immigration warrant, according to court papers, and was charged with illegal gun possession after agents found several firearms during the search of his home. Bondi said he was living in the U.S. illegally.

There was no attorney listed for him in the court docket. Telephone numbers for relatives could not immediately be found in public records.

Administration’s Crackdown on MS-13

The administration promoted the arrest as part of its effort to fulfill campaign promises to quash illegal immigration and eliminate gangs. MS-13 gang, or Mara Salvatrucha, was one of eight Latin American criminal organizations declared foreign terrorist organizations by the Trump administration last month.

“We want to make our streets safer,” Bondi told reporters. “We want to make our schools safer. We want to make your neighborhoods safer. This guy was living in a neighborhood right around you, no longer.”

At the White House, press secretary Karoline Leavitt, citing the arrest, called it “a good day for our country.”

MS-13’s History and Impact

In the past decade, the U.S. Justice Department has intensified its focus on MS-13, which originated as a neighborhood street gang in Los Angeles, but grew into a transnational gang based in El Salvador. It has members in Honduras, Guatemala and Mexico and thousands of members across the U.S. with numerous branches, or “cliques.”

The 2016 killings of two high school girls, who were hacked and beaten to death as they walked through their neighborhood on New York’s Long Island, focused national attention on the gang. Nisa Mickens, 15, and Kayla Cuevas, 16, friends and classmates at Brentwood High School, were killed with a machete and a baseball bat by a group of young men and teenage boys who had stalked them from a car. More killings followed in the coming months.

President Donald Trump has blamed the violence and gang growth on lax immigration policies. In his first term as president, Trump promised an all-out fight against MS-13, saying he would “dismantle, decimate and eradicate” the gang.

Leavitt is one of three Trump administration officials who face a lawsuit from The Associated Press on First and Fifth Amendment grounds. The AP says the three are punishing the news agency for editorial decisions they oppose. The White House says the AP is not following an executive order to refer to the Gulf of Mexico as the Gulf of America.
