A U.S. Air Force helicopter made an emergency landing in Washington, D.C., on Monday after its pilots detected unusual mechanical noises during flight.
Air Force public affairs chief Ann Stefanek confirmed the incident in a statement and said there were no injuries. Several law enforcement agencies responded, including the FBI and the Metropolitan Police Department.
Stefanek said the aircraft was conducting a routine training mission when the crew noticed a possible mechanical problem. After hearing the abnormal sounds, the pilots landed as a precaution, following standard training procedures. No damage was reported.
The UH-1N helicopter, assigned to the First Helicopter Squadron at Joint Base Andrews, was carrying four personnel at the time.
The emergency landing occurred on the same day police took an armed man into custody after he drove up to a security barricade near the U.S. Capitol.
According to U.S. Capitol Police, officers arrested the man at the North Barricade after finding that he was carrying a firearm.

Because firearms are banned on Capitol Grounds, officials quickly shut down the area while investigators examined the scene.
“Our investigators are working to learn more about the suspect and why he drove to the U.S. Capitol,” Capitol Police said in a statement.
Police remained at the scene throughout Monday afternoon, where officers were seen removing items from a Ford Bronco parked diagonally in front of the barricade.
Fox News obtained video showing the suspect’s Ford Bronco being towed away from the North Barricade following the arrest.
The SUV, which displayed Florida license plates, was removed from the scene by authorities as investigators continued processing evidence and working to determine why the armed man drove to the U.S. Capitol.
