A Florida sheriff says there are “no signs of an active shooter” and no injuries after police responded to a report of gunshots at the Corry Station, a Navy installation in Pensacola.

Sheriff Chip Simmons says someone reported hearing multiple gunshots on Thursday, but officers have conducted a search and found no evidence of a shooting and no victims.

The base and Naval Air Station Pensacola had closed entrances as police investigated. Simmons said officers are continuing to conduct a comprehensive sweep of the base.
