The US Naval Academy in Maryland was placed on lockdown on Thursday evening following reports of an armed intruder, but state officials have confirmed there was no credible threat.
The lockdown was triggered after a former midshipman, who had been expelled, made anonymous threats on social media, using an IP address that suggested he was on campus. However, authorities later determined the threat was not credible.
During the incident, a midshipman mistakenly believed a law enforcement officer was a threat and struck the officer with a training weapon. In response, an officer accidentally discharged their firearm, injuring the midshipman in the shoulder. The injury is believed to be non-life-threatening.
Rumours that an active shooter was impersonating police on campus were also found to be false. The academy later issued a security update to midshipmen confirming the rumours were untrue.
The lockdown occurred on the same day as a non-credible bomb threat at the Democratic National Committee headquarters in Washington, D.C., and a day after the assassination of conservative activist Charlie Kirk in Utah.
