An unarmed man who broke through two sets of glass doors at the Fox 5 studio in Washington, D.C., Monday afternoon was shot by a private security guard and taken to a hospital for his injuries, according to a Metro Police Department spokesman.

The suspected intruder at WTTG was identified as a 38-year-old man, according to a report the network published shortly after police secured the scene.

Multiple reporters at the studio shared on Twitter that the man had tried to break through the two sets of glass doors at the front of the building on the corner of Harrison Street and Wisconsin Avenue NW shortly after 3 p.m. ET.

Video aired on Fox 5 showed an African-American man in a red sweatshirt standing with his back to the first glass door kick his foot into the glass, breaking it. He then walked through to the second set of doors which he also kicked through.

Reporters said the security guard then shot the suspect.

Police have not shared what they believe was the suspect's motive. Commander Melvin Gresham confirmed during a press briefing that the suspect did not have a gun on him.

One reporter, Marina Marraco, said on air the man appeared to be having "some sort of mental episode" prior to being shot.

Police responded to the incident and the unnamed suspect was seen being rolled on a stretcher to an ambulance. He was conscious and had an oxygen mask on his face.

Marraco said he was shot in the upper chest but did not go into further detail on the man's injuries.

In late June, a gunman entered the Capitol Gazette newsroom in Annapolis, Md., opened fire on reporters, editors, and other staff. Five people were killed in the incident.
