A federal grand jury indicted four suspected members of an anti-government activist group on terrorism-related felonies for their alleged involvement in a thwarted bombing plot targeting various businesses across Los Angeles.

Audrey Illeene Carroll, Zachary Aaron Page, Dante James Anthony-Gaffield, and Tina Cheng-Ting Lai are facing charges of providing and attempting to provide material support to terrorists, plus possession of unregistered firearms, according to the six-count indictment returned on Tuesday.
