Joint Base Anacostia-Bolling in Washington, DC, was on lockdown for about two-and-a-half hours on Friday afternoon.

The base was locked down over a "potential armed individual," First Lt. Cali Gradishar, the base's chief of public affairs, told Insider.

The police were called over reports of a shooting at 3800 Halley Terrace SE at 12:04 p.m., where they found evidence of a shooting, but no victim, Officer Makhetha Watson of the Metropolitan Police Department told Insider. After the call, the suspect ran from his location to the base, Watson said.

On its Facebook page, the military base warned anyone who encountered the suspect to run, hide, or fight, a common piece of advice in shootings.

As of 3:02 p.m., the base issued an all-clear and reported that "the individual was detained and will be transferred to Metropolitan Police Department custody." First responders are still assessing the situation, the base said.

There were no initial reports of injuries, a military spokesperson told Military.com reporter Steve Benyon.
