The Latest: UK base incident not being treated as terrorism

LONDON – The Latest on the police response at a British air base used by U.S. Air Force (all times local):

6:30 p.m.

British police investigating what they called a disturbance at an English military air base used by the U.S. Air Force say the incident is not being treated as terrorism.

Suffolk Police said a 44-year-old British man was arrested earlier Monday at the RAF Mildenhall air base "on suspicion of criminal trespass."

The facility was placed under lockdown briefly and American service members fired shots during the incident, police said. It remains unclear what the nature of the disturbance was but British media reported that a man had tried to ram the gates of the facility. Police and officials at Mildenhall declined to comment on the reports.

Police said there is no threat to the public or those on the base, and they are not looking for anyone else on the site in relation to the incident.

A British air base used by the U.S. Air Force was scouted out in 2015 by an Islamic extremist who eventually received a life sentence for plotting an attack against U.S. military personnel.

Junead Khan was tried for using his job as a delivery driver to study RAF Mildenhall, the base in England that was locked down on Monday during a disturbance that resulted in a man's arrest.

Authorities have not said if the incident at Mildenhall was suspected to be terror-related. Details have not yet been released.

A jury convicted Khan last year of planning to travel to Syria as a support of the Islamic State group and preparing possible attacks at Mildenhall and a second English base, RAF Lakenheath.
