A disturbing terror plot targeting a Jewish community in Houston has been thwarted, after law enforcement arrested multiple suspects accused of planning a mass casualty attack at a synagogue.

One of the arrests is of 18 year old Angelina Han Hicks of North Carolina, who has been charged with felony conspiracy to commit murder and assault with a deadly weapon. According to court documents, the plan was to “kill as many Jews as possible” by driving a vehicle directly into a shul at Congregation Beth Israel in Houston.

Authorities say Hicks was not acting alone. Investigators revealed she was working with at least two other individuals, while a 16 year old suspect in Texas has already been arrested and charged in connection with the plot.

The investigation began after a tip was received by law enforcement, triggering a multi-state response involving the FBI and local agencies. Officials moved quickly, and arrested Hicks in her house and uncovering what they described as a credible and dangerous plan in development. The threat was taken as immediate and serious, not something distant or theoretical.

In response to the threat, the shul and associated Jewish school temporarily shut down out of an abundance of caution, as authorities worked to make sure there was no ongoing danger.

Hicks is currently being held on a $10 million bond, which shows the severity of the charges.
