Two Just Stop Oil supporters have sprayed private jets with orange paint at an airfield where Taylor Swift's planes are believed to be parked.
The climate activist group shared a video of two members cutting into a private airfield at Stansted on Thursday morning and vandalising the planes using fire extinguishers filled with orange paint.
Stansted airport confirmed Essex police have arrested two people for entering the private aviation area this morning.
Swift, currently touring the UK, has been criticised for her carbon footprint due to her extensive use of private jets. It is not known who the jets targeted belong to.
The group are demanding that the incoming UK government commit to working with other governments to agree an equitable plan to end the extraction and burning of oil, gas and coal by 2030.
Activist Cole Macdonald, 22, from Brighton, said 'We're living in two worlds: one where billionaires live in luxury, able to fly in private jets away from the other, where unlivable conditions are being imposed on countless millions.
'Meanwhile, this system that is allowing extreme wealth to be accrued by a few, to the detriment of everyone else, is destroying the conditions necessary to support human life in a rapidly accelerating never-ending "cruel summer".
'Billionaires are not untouchable, climate breakdown will affect every single one of us.'
The activists Jennifer and Cole cut the fence into the private airfield at Stansted where Taylor Swift's jet is parked, demanding an emergency treaty to end fossil fuels by 2030.
Taylor Swift is performing at Wembley Arena this weekend, after already touring in the UK across Edinburgh, Liverpool and Cardiff this month.
