It appears that authorities have finally caught up with Patrik Mathews, the Canadian military reservist who went on the lam after authorities found out about his activities in the neo-Nazi organization The Base. And it may have been just in the nick of time.

The FBI announced today that it had arrested Mathews, along with two other members of The Base. They were planning acts of violence around Monday’s planned protest in Richmond, Virginia, against gun control measures being planned by the Virginia Legislature.

Brian Mark Lemley of Elkton, Maryland and Newark, Delaware, and William Garfield Bilbrough IV of Denton, Maryland, were the two other men charged, according to the U.S. Attorney's office in Maryland, the state where the men were based.

The complaint unsealed Thursday says Lemley and Mathews transported a firearm and ammunition “with intent to commit a felony.” It also charges Lemley and Bilbrough with transporting and harboring aliens, as well as conspiracy to do so.

According to the affidavit, Lemley and Mathews bought about 1,650 rounds of 5.56mm and 6.5mm ammunition for their planned trip to Virginia to participate in the anti-gun-control rally.

Concerned about the presence of such extremists and the violent rhetoric on social media surrounding the protest, Virginia Gov. Ralph Northam on Wednesday declared a state of emergency, and announced that firearms would be prohibited from the Capitol grounds on Monday.
