A woman threw ''£5,000 in cash'' at a man on an airport runway - after they were escorted off a plane, passengers claim.

The flight had to be diverted after the couple had a fierce argument, onlookers said.

Holidaymakers say troubled flared when they were five hours into the 9.35pm flight from Heathrow to Bangkok on September 30.

They said the couple had a blazing row and the pilot told passengers for safety he would have to turn back and land in Vienna, Austria - which would take an extra two and a half hours.

Videos show police escorting the pair off of the flight - but then on the runway she appears to throw cash at him.
