The US Air Force Academy reported on Twitter that there is an active shooter on its grounds. Police have been searching the dorms of the military school for about an hour and reported no suspect was found.
The academy in Colorado was placed on lockdown at around 10 p.m. MDT, and warning text messages were sent to airmen informing them of the incident, AP reports citing authorities.
El Paso County Sheriff's Office said on Twitter that military personnel and police were clearing dorms, and that there were no reported injuries.
Within an hour of El Paso police tweeting about the investigation of the incident, a search of the academy dorms was completed, according to County Sheriff's Office.
The US Air Force Academy later reported on Twitter that “everyone is safe” and said that no shots or injuries had been confirmed. In a separate post, it said that the cause of the reports will be further investigated.
Prior to the incident, the chief of the Air Force Academy gave a speech speech over a scandal that was unveiled earlier this week. Racial slurs had been written on message boards at the academy's preparatory school.
“You should be outraged as an airman and as a human being,” Lt. Gen. Jay B. Silveria told his audience of cadets and officers on Friday.
“If you can't treat someone from another race or a different color skin with dignity and respect then you need to get out," the superintendent said.
