Anti-fascist activists in Virginia have published allegations linking a Virginia Capitol Police sergeant to white nationalists. He's since been placed on paid leave.

The Virginia Division of Capitol Police said in a release Wednesday they are investigating whether Sgt. Robert A. Stamm violated unspecified policy.

On Tuesday, the Antifascists of Seven Hills published links to Stamm's social media accounts and described his tattoos. Their blog post said social media activity suggests Stamm follows the Asatru Folk Assembly, which the Southern Poverty Law Center describes as a hate group blending northern European paganism and ethnocentrism.

The anti-fascist group says Stamm caught their attention while monitoring protests calling for Virginia Gov. Ralph Northam's removal over a racist photo in his 1984 yearbook, the Richmond-Times Dispatch reports.

The newspaper couldn't immediately reach Stamm for comment.
