LIVE COVERAGE: Five fatalities confirmed after shooting at Capital Gazette newspaper in Annapolis

Five people are dead after a shooting inside the newsroom of the Capital Gazette newspaper in Annapolis, Maryland.

Police reportedly have a suspect in custody, who is a white male in his 20s. A shotgun was involved in the incident.

An intern for the paper, which is owned by The Baltimore Sun, tweeted "Active shooter 888 Bestgate please help us."

Capital-Gazette crime reporter Phil Davis tweeted "A single shooter shot multiple people at my office, some of whom are dead."

"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."

"There is nothing more terrifying than hearing multiple people get shot while you're under your desk and then hear the gunman reload," Davis said.

He told the Baltimore Sun that the scene "was like a war zone."

“I’m a police reporter. I write about this stuff — not necessarily to this extent, but shootings and death — all the time,” he said. “But as much as I’m going to try to articulate how traumatizing it is to be hiding under your desk, you don’t know until you’re there and you feel helpless.”

The Bureau of Alcohol, Tobacco, Firearms and Explosives also responded to the incident.

Gov. Larry Hogan tweeted: "Absolutely devastated to learn of this tragedy in Annapolis."
