PA MediaGreta Thunberg has been arrested at a demonstration in support of the Palestine Action protesters who are on hunger strike in prison, according to the Prisoners for Palestine protest group.
The 22-year-old activist was detained in the City of London after attending the scene of the early-morning demonstration on Fenchurch Street.
In a video shared by the group, she could be seen holding a sign reading “I support the Palestine Action prisoners” and “I oppose genocide”.
City of London Police said a 22-year-old woman was arrested for displaying a placard in support of a proscribed organisation, in this case Palestine Action, contrary to Section 13 of the Terrorism Act 2000.
The force said officers were called to the area at about 07:00 GMT after hammers and red paint were used to damage a building.
A man and a woman were also arrested on suspicion of criminal damage after they “glued themselves nearby”, police said. Specialist officers worked to release them before taking them into custody.
PA MediaThe Prisoners for Palestine protest group said it staged the demonstration outside the offices of Aspen Insurance, which it claimed provides services to Israeli-linked defence firm Elbit Systems.
Palestine Action was proscribed under UK terrorism legislation earlier this year, making it a criminal offence to support or express support for the group.
Police said inquiries were continuing.
Ms Thunberg, who first came to prominence as a child climate activist, has been involved in several demonstrations in support of the Palestinian cause.
