A Texas city council candidate was arrested Saturday morning on a misdemeanor charge for “riot participation” in connection with behavior authorities said they observed at a protest against the shooting of a Venezuelan man by a federal immigration officer.

Texas Department of Public Safety troopers and special agents took Misael Ramos, 40, into custody around 8:45 a.m. Saturday on an outstanding warrant “stemming from his actions” during a Sunday protest, the agency’s media department wrote in an unsigned email. Protesters on Sunday had been demonstrating against the shooting of Wilber Rafael Garces Perez in Austin.

Ramos, who is running for city council in Austin, “was captured on camera taking construction barricades, sandbags, and other items and attempting to obstruct traffic,” the department said. The department also provided photos and video it said captured “some of Ramos’ actions” at the scene.
