There were 170 people in the building, the publication wrote. The Baltimore Sun-owned paper quoted police as saying a “long gun” was used in the incident, an “explosive device” was seized. Law enforcement in Baltimore and New York City deployed protective forces to major media outlets, including the New York Times, as a precaution, authorities said. A member of the NYPD stands guard in front of ABC headquarters in New York City as they increase security in Manhattan at major media companies following a shooting today at the Capital Gazette newspaper in Maryland, June 28, 2018. “The shooter is in custody and is being interrogated at this time,” Steve Schuh, the county executive of Anne Arundel, told a news conference. Maryland Governor Larry Hogan said at the news conference: “It’s a tragic situation. We don’t have all the information yet, and we can’t give all the information yet, but we have had several fatalities.” Previously, the local ABC7 news reported "multiple fatalities", quoting police in the historic city located an hour east of Washington. For now, the Annapolis shooting is being treated as a local incident and not one that involves terrorism, a law enforcement official said. The Federal Bureau of Investigation (FBI) is on the scene assisting local authorities, the official said. After initially informing people via Twitter of the shooting, Phil Davis, a crime reporter at the Capital Gazette, said his office “was like a war zone”, an incident he would find “hard to describe for a while”, according to the publication's report.
