Two reputed white supremacists have been arrested in Virginia for allegedly plotting to attack black churches and Jewish synagogues, according to federal authorities.

Robert Curtis Doyle and Ronald Beasley Chaney III were arrested Sunday after a months-long investigation that sent FBI agents in to disrupt a plan allegedly already underway, according to charging documents filed in federal court.

In late September, the FBI received a tip that Doyle and Chaney would be meeting the next week to discuss a plot to shoot or bomb worshippers inside black churches and Jewish synagogues, and to attack a specific gun store owner in Oklahoma, according to the FBI.
