PASSENGERS at Stansted Airport were delayed by up to an hour after people arriving on a Ryanair flight went through an exit door "left open in error".

Stansted said passengers arriving on the Lisbon flight at 9.20am yesterday had to be processed by departures security before moving to arrivals, causing delays.

Ryanair said its crew had disembarked passengers "to the assigned gate".

An investigation into the incident is being conducted by the airport.

A Ryanair spokesman said: "The crew of this flight correctly directed disembarking customers to the assigned gate."
