LONDON – Climate campaigner Greta Thunberg was charged with a public order offence by London police on Wednesday after she and others were detained at a protest outside an oil and gas conference being held at a luxury hotel the previous day.

Thunberg, 20, was charged with failing to comply with conditions that police said had been imposed to prevent “serious disruption to the community, hotel and guests.” She has been released on bail and is due in court on Nov. 15.

Twenty-five other individuals were also charged in relation to Tuesday’s protest, police said.

Thunberg joined hundreds of activists to protest outside the InterContinental Hotel in Mayfair where the Energy Intelligence Forum was hosting a gathering of oil and gas industry leaders on Tuesday. The demonstrators locked their arms to block the entrance to the hotel, preventing two delegates from entering.

Thunberg, who rose to fame in 2018 when she organised school walkouts to protest inaction on climate change, has been detained by police or removed from protests in Sweden, Norway and Germany this year, and she has twice been found guilty of disobeying police orders.

Earlier this month, Thunberg was fined 4,500 Swedish crowns ($414) for failing to leave a protest in July when police ordered her to do so. It was the second time she had been fined for the same offence.

On July 24, Thunberg and other activists from the environmental group Reclaim the Future blocked the road as oil trucks tried to drive to Malmo harbour and were forcibly removed by police, only hours after she was convicted and fined for a similar action in June.

Here’s a timeline of Thunberg’s rise from solo climate striker to leading global campaigner:

Week 258. The UK gov & Norwegian state-owned oil giant @Equinor want to build the massive Rosebank oil field. It would produce more CO2 than the 28 lowest income countries do in a year, burning us past climate targets and do nothing to lower energy bills.#StopRosebank @stopcambo pic.twitter.com/seH7jd3CQ6
