A Just Stop Oil protester who grounded Heathrow flights after scaling the M25's gantry has been found guilty of causing public nuisance.
Cressida Gethin, 22, a music student at Cambridge University, was convicted of causing a public nuisance contrary to the Police, Crime, Sentencing and Courts Act 2022.
The jury at Isleworth Crown Court delivered its verdict by a majority of 10 to two.
Gethin's actions on July 20, 2022, delayed 3,923 British Airways passengers’ journeys.

Gethin was keen to stress the consequence did not amount to the charge.
However, the student did not dispute scaling the gantry near the UK's busiest airport.
Gethin, who was self-represented, told the court in her closing statement: “If you believed that the protest causing the delays was intended to create meaningful, positive change, would you have defined the delay as ‘serious inconvenience’?
