Palm Beach County Sheriff Ric Bradshaw said at a news conference Sunday afternoon that the gunman got as close as 300 to 500 yards away from the former president when he was spotted, and agents fired four to six rounds at him before he dropped the gun and fled. It was not clear if the suspect was aiming his weapon at Trump.

U.S. Secret Service agents fired at the suspect after seeing his rifle through the fence line, multiple sources told ABC News.

After being shot at by Secret Service agents, officials said that the suspect got into a vehicle, and witnesses reported the license plate number, which was tracked by authorities. Bradshaw said that the suspect was stopped and taken into custody.

He also said that along with an “AK-47-style rifle,” two backpacks were found at the scene with a GoPro camera and ceramic tiles inside.

According to sources, three shell casings believed to be associated with the suspect’s AK-47 were found on the scene. However, sources said investigators are still evaluating whether the suspect discharged his weapon at the location.
