A man seen tossing a brick through the window of the Robert Nix Federal Building just before 9 p.m. was identified as 25-year-old Adam McVicker, of Coatesville, police said.
McVicker, along with Dustin Callahan, 24, of Farmingdale, NJ; Allison Donohue, 23, of Wallingford; and Josey Augustine, 31, of Royersford were charged with criminal mischief and related offenses, authorities said.
Three other people were charged in a separate incident, during which they spray-painted anti-police and anti-prison graffiti on the building's walls, police said.
More windows were broken and a sheriff's van was also defaced, according to police.
Jacob Robotin, 25, of Willow Grove; Sydney Miller, 22, of Philadelphia; and Meredith Tooker, 26, were charged with attempted arson, risking catastrophe, having an incendiary device, conspiracy and more.
Robotin was found in possession of a glass jar that had a "strong flammable odor" and fuse, along with a plastic container of white powder labeled "fire starter," authorities said.
Miller was in possession of bottled-up liquids that had “a chemical smell," according to police.
Authorities recovered "numerous Molotov cocktails” and other suspicious devices, Chief Inspector Mike Cram said.
