A bomb disposal police unit has been sent to Gatwick Airport after a “suspected prohibited item” was found in luggage.
Sussex Police said a “security cordon has been put in place” inside the south terminal of the UK’s second busiest airport.
A large part of the building has been evacuated.
Around 100,000 passengers are set to fly in and out of the airport on Friday, but many are likely to be missing their flights.
Flights continue to depart from the south terminal, but are only carrying passengers who had passed through security before the incident began.
Sussex Police said in a statement: “Police were called to the south terminal at Gatwick Airport at 8.20am on Friday following the discovery of a suspected prohibited item in luggage.
“To ensure the safety of the public, staff and other airport users, a security cordon has been put in place whilst the matter is dealt with.
“As a precaution, an EOD (explosive ordnance disposal) team is being deployed to the airport.
“This is causing significant disruption and some roads around the south terminal have been closed.
“We’d advise the public to avoid the area where possible.”
A large part of the South Terminal has been evacuated as a precaution while we continue to investigate a security incident.

The north terminal is unaffected.
Nejadeen Braham, 35, who works as a nurse on the Isle of Man, was due to fly to her homeland of Jamaica to collect her children.
Speaking to the PA news agency outside the south terminal, she said: “I couldn’t get in the airport. I saw everybody coming (out) from one direction.
“I was supposed to go inside, drop my bags and go through security.
“When I got here I saw everybody coming down.
“There were no proper updates.
“I m very frustrated.”
British Airways said in a statement it is “in contact with affected customers and giving them updates as and when we can”.
It went on: “We’re also providing them with options including flight re-bookings and hotel accommodation where necessary.
“We ask customers to check ba.com for the latest flight information before coming to the airport.”
