The man arrested Friday afternoon while carrying a shotgun near First and D streets Northeast was charged as a felon in possession of a firearm after officers spent the afternoon questioning him and determining whether a green pickup truck “associated” with him was a threat. Capitol Police cordoned off several blocks after taking into custody Michael Steven Gorbey, 38. Other charges are pending, according to a statement from Capitol Police spokeswoman Sgt. Kimberly Schneider. Officers arrested Gorbey around 1 p.m. Friday after they saw him walking south on First Street carrying not only a shotgun but also a sword. No shots were fired and no one was injured during the arrest. Several police officers were required to detain the man. The green pickup truck was under investigation Friday by the Capitol Police bomb squad after officers reported seeing wires in the truck that could have been part of an explosive device. Late that afternoon, bomb squad members created a loud boom in an attempt to trigger any potential explosive. Bystanders reported hearing only the boom, but no explosion. Television footage later showed a bomb squad officer walking around the vehicle, whose driver-side door was open and contents were scattered on the street. Late Friday night, Capitol Police deemed the vehicle safe, but the incident is still under investigation. Earlier in the day at a mid-afternoon news conference, Schneider said police were investigating the vehicle to determine if there was anything inside “of a hazardous or suspicious nature.” Part of the investigation was performed by a bomb squad robot. “Our main concern right now is to make sure the public is safe,” Schneider said at the news conference, explaining why police had cordoned off what she called a “huge perimeter.” Officers closed off a large area roughly bordered by Union Station on the north and Constitution Avenue on the south. Streets also were blocked off as far west as First Street Northwest. One side of the Teamsters building near Louisiana Avenue Northwest also was evacuated before bomb squad officers were able to test the car for any explosive device. — Elizabeth Brotherton and Emily Yehle
