Gatwick North Terminal has been evacuated after a terror scare.

Witnesses said that armed police arrested a man with a 'gun in a bag' and screamed 'get down, get down' before they restrained him.

Twitter user Mari Reynolds posted a message saying that a 'lockdown is in progress'.

Eyewitness Tim Unwin tweeted that the terminal is in a 'shutdown situation'.

Sussex Police told MailOnline: 'We are dealing with an incident involving a suspicious article and have evacuated the North Terminal as a precaution.'
