Law enforcement officials completed a search early Saturday and found no evidence of an active shooter at an Air Force Academy dormitory.

Authorities said that the Colorado-based academy was placed on lockdown after 12 a.m. ET, and that text messages were sent to airmen warning them of a possible shooter. The Air Force Academy later provided the all-clear, saying on Twitter that there were “no confirmed shots fired” and that “everyone is safe.”

“We will continue to investigate the cause of the reports.” the Air Force Academy said on Twitter, adding: “We would like to thank our community partners for their assistance.” – READ MORE
