Federal U.S. authorities on Monday announced the arrests of four alleged members of an extremist group suspected of planning coordinated bombing attacks on New Year’s Eve across Southern California.

The suspects were arrested last week in Lucerne Valley, a desert city east of Los Angeles, where they were allegedly preparing improvised explosive devices ahead of the planned attacks, according to a federal criminal complaint filed Saturday.

They are members of an offshoot of a pro-Palestinian group dubbed the Turtle Island Liberation Front, the complaint said.

They each face charges including conspiracy and possession of a destructive device, court documents show.

FBI Director Kash Patel said the group planned five attacks across Los Angeles and added that a fifth individual was arrested in New Orleans for planning a separate attack.

Attorney General Pam Bondi referred to the group as “far-left, pro-Palestine, anti-government, and anti-capitalist,” adding that they had plotted “what would have been a massive and horrific terror plot” on multiple targets on New Year’s Eve, including ICE agents and vehicles.

Evidence photos included in the court documents show a desert campsite with what investigators said were bomb-making materials strewn across plastic folding tables.

The suspects “all brought bomb-making components to the campsite, including various sizes of PVC pipes, suspected potassium nitrate, charcoal, charcoal powder, sulfur powder, and material to be used as fuses, among others,” the complaint states.

Federal authorities planned a Monday morning news conference to discuss the arrests.

The four defendants named in the complaint are Audrey Illeene Carroll, 30, Zachary Aaron Page, 32, Dante Gaffield, 24, and 41-year-old Tina Lai.

According to a sworn statement in support of the complaint, in November Carroll presented an eight-page handwritten document to a paid confidential source titled “Operation Midnight Sun” which described a bomb plot.

Carroll and Page later allegedly recruited the other two defendants to help carry out the plan, which included them “acquiring bomb-making materials and traveling to a remote location in the Mojave Desert to construct and detonate test explosive devices on December 12, 2025,” the sworn statement alleges.

FBI agents intervened before they could complete their work to assemble a functional explosive device.
