A man has been arrested after apparently trying to drive through a checkpoint at a base used by the US air force in Suffolk.
RAF Mildenhall was put into lockdown as police responded to reports of what they called a “significant incident”.
A person was arrested and is now in the custody of Suffolk Police.
A US military statement said the base was locked down at 13:00 GMT “following reports of a disturbance” and emergency personnel were deployed.
The security alert was later ended.
Suffolk police are currently at the scene and are advising people to avoid the area for the time being.
RAF Mildenhall is used as a transport hub by the USAF and is home to the KC-135 tanker fleet and special operations forces.
It has about 3,200 military personnel, with 400-500 UK civilian staff employed there.
The US Air Force said in September it was delaying plans to relocate operations to a base in Germany until 2024.
