A plane bound for New York had to return to Heathrow Airport after a laser was shone at the cockpit.
The Virgin Atlantic flight doubled back as a "precautionary measure" after the co-pilot reported feeling unwell following the incident, the airline said.
Police said they were trying to find the source of the beam.
A Virgin Atlantic spokeswoman said: "The VS025 travelling from London Heathrow to New York JFK flight has returned to Heathrow as a precautionary measure due to a laser beam incident.

"The safety of our crew and customers is our top priority and we apologise for any inconvenience to those on board.
