Blind Paralympian climbs a British Airways Plane
Organizers said at least 60 people were arrested as they blocked roads and pathways.
Brown, a partially blind former Paralympic cyclist, got on top of the aircraft after buying a ticket for the flight, halting its departure. A second ticket-holding protester boarded an Aer Lingus flight, then refused to sit and calmly spoke out about climate change risks. Both were arrested and removed.
Extinction Rebellion organizers said the protest had caused "major disruption" but had not shut down the airport as they had hoped.
London's Metropolitan Police, on their website, called the airport protest "wholly unacceptable and irresponsible". They noted that more than 840 people had been arrested in four days of Extinction Rebellion protests across the capital this week.
