A passenger was arrested at Heathrow Airport after a woman said she was raped in business class on an overnight transatlantic flight from New Jersey.
The woman said she was attacked by a 40-year-old man while others slept on the flight from Newark on 31 January.
Officers boarded the United Airlines plane after it landed at 06:39 GMT and arrested the man who has since been released under investigation.
The Met Police said the woman was being supported by specialist officers.
A spokesman said the Met was aware of “an incident on an inbound flight”.
