The U.S. Naval Academy in Annapolis, Maryland, was placed on lockdown on September 11, 2025, due to reports of threats made against the academy. The lockdown was initiated as a precautionary measure while authorities investigated suspicious activity on the grounds. The incident involved misinformation from an anonymous messaging platform about a potential active shooter, which was traced to a former midshipman who had already left the academy. During the confusion, a midshipman mistook authorized law enforcement officers for the threat and engaged them, resulting in injuries to both the midshipman and a law enforcement officer. The midshipman was injured in the arm and is in stable condition, receiving medical care. There was no active shooter on campus, and the threat was confirmed to be false. The academy was on lockdown out of an abundance of caution while law enforcement and Naval Security Forces cleared and secured the buildings, including Bancroft Hall, which houses over 1,600 midshipmen. The situation was evolving with ongoing coordination between the Naval Academy and local law enforcement, and updates were promised as they became available.
