An Easyjet flight on route from Hamburg to Luton with 151 passengers on board has been diverted to Stansted Airport following a security alert.
The plane landed at 17:20 BST, a Stansted spokesman told the BBC.
Essex Police later said the passengers were safe and well and the plane was expected to be cleared to fly to Luton.
In a statement later Easyjet said the Airbus A319 aircraft had been diverted as a "precautionary measure".
"We would like to thank passengers for their patience and apologise for any inconvenience caused," it said.
