COLLEGE PARK, Md. (AP) — FBI agents on Thursday arrested a former Canadian Armed Forces reservist and two other men who are linked to a violent white supremacist group and were believed to be heading to a pro-gun rally next week in Virginia’s capital.

The three men are members of The Base and were arrested on federal charges in a criminal complaint unsealed in Maryland, according to a Justice Department news release.

Tuesday’s complaint charges Canadian national Patrik Jordan Mathews, 27, and Brian Mark Lemley Jr., 33, of Elkton, Maryland, with transporting a firearm and ammunition with intent to commit a felony. William Garfield Bilbrough IV, 19, of Denton, Maryland, is charged with “ transporting and harboring aliens.”
