Police arrested Extinction Rebellion protesters outside London City Airport on Thursday (October 10) and removed one that had invaded the roof of the airport.
Some protesters criticised the police for "dragging" those that were arrested, but the crowd chanted "police, we love you, we're doing this for your children".
The activists were heckled by a climate change denier who yelled: "Climate change is a massive hoax."
He also shouted: "Trying to run the Earth and planet - Mother Earth, that's why you're into it.
"You poor men, being led around by these silly women. Oh, you men need to get some balls!"
