Wednesday 8th January: Departures at Heathrow have been stopped after a drone was sighted, the airport says.
A Heathrow spokeswoman said the airport was working with police to “prevent any threat to operational safety”.
“As a precautionary measure, we have stopped departures while we investigate. We apologise to passengers for any inconvenience this may cause.”
It comes after last month’s disruption at Gatwick Airport after drones were reported.
