Police in Panama City, Florida, said on Tuesday they were responding to a suspected active shooter in an apartment complex.
Local media reported a large police presence at the complex. Bay County Sheriff's Office and Panama City Police Department responded to the scene, sheriff's spokeswoman Ruth Corley said in a phone interview.
Local media footage showed several officers with weapons drawn taking cover behind cars. What sounded like gunshots could be heard as a local television reporter conducted a live interview with a witness who said he had heard gunfire.
Panama City is located on Florida's panhandle about 80 miles (129 km) west of Tallahassee.
