HS2 Rebellion protesters have climbed onto the top of the controversial rail line's headquarters and used modified fire extinguishers to paint it pink.
Xavier Gonzalez Trimmer, 20, and Dr Larch Maxey, 48, clambered onto the canopy of building's lobby in Euston, central London, at 10am this morning clutching industrial spray paint machines.
Footage shows the pair showering the facade of the building in neon pink paint, to show their support of the Burning Pink Party, as police tell onlookers to stand back.
A fire engine and at least three police officers were at the scene this morning as the protesters tried to stop the development of the HS2 railway, claiming it will emit 14million tonnes of CO2.
