Shooting at Capital Gazette newsroom in Maryland

At least five people were killed and several others were “gravely injured” in a shooting Thursday afternoon at the Capital Gazette in Anne Arundel County, authorities said.

A shooter is in custody, police said. Police would not name the suspect or say what type of weapon was used.

Anne Arundel County Police initially confirmed about 3:15 p.m. that they were responding to an “active shooter” at 888 Bestgate Road, where the newspaper’s offices are located. The Bureau of Alcohol, Tobacco, Firearms and Explosives also responded to the scene.

The Capital Gazette is owned by The Baltimore Sun.

Police said a “long gun” was used in the incident. They said officers did not exchange gunfire with the suspect, who was now being interrogated. They said officers had recovered what appeared to be an “explosive device,” and had “tactically secured” the building. About 170 people were inside at the time of the shooting, police said.

Phil Davis, a Capital Gazette crime reporter who was in the building at the time of the shooting, said multiple people were shot, as others — himself included — hid under their desks. He said there was a lone male gunman.

“Gunman shot through the glass door to the office and opened fire on multiple employees. Can’t say much more and don’t want to declare anyone dead, but it’s bad,” Davis wrote on Twitter as he waited to be interviewed by police.

“There is nothing more terrifying than hearing multiple people get shot while you’re under your desk and then hear the gunman reload.”

In a subsequent interview, Davis said it “was like a war zone” inside the newspaper’s offices — a situation that would be “hard to describe for a while.”
