The 31-year-old from London was picked up by officers after they were called at 2.26am yesterday to reports that an intruder got into a secure part of the site.

He went into a hangar and approached two workers, assaulting one with a mug and another with what was believed to be a piece of broken glass. The men suffered minor cuts and bruises, which did not require medical treatment.

The suspect then approached a lorry, which was stationary, and got into the cab before making threats to a member of security staff who was nearby. Officers arrived and held the man, who did not drive the lorry.

The man was taken to Wymondham Police Investigation Centre for questioning, where he was deemed unfit to be interviewed after undergoing a mental health assessment.

He has been returned to Norwich Prison while investigations continue into the circumstances surrounding the incident.

A police spokesman said: 'This is not being treated as a terror-related incident and police are not looking for anyone else in connection with it.

'A seal was put in place at the hangar while enquiries were carried out; however this has now been lifted. The incident did not affect any public areas of the site and the airport remains open and flights are operating as normal.'

Earlier, Supt Dave Marshall, Norwich policing commander, said: 'The incident was resolved promptly with officers on scene within eight minutes of the 999 call being made and the suspect detained at 2.41am.

'We are treating this as an isolated incident and we are not looking for anyone else in connection with it. This is not currently being treated as a terror-related incident.'

Ross McDermott, head of aviation and specialist services with Dardan Security, which is involved in security at the site, said: 'Clearly we're all very aware of the security threat on an aviation site and it's now a case of working together when we know more to pick up any potential lessons learned and make sure we address any security measures accordingly.'
