London police on Tuesday, January 23, arrested Swedish activist Greta Thunberg at a demonstration in support of pro-Palestinian hunger strikers, Palestinian campaign groups said. Thunberg's arrest makes her the highest-profile person to be detained by police since the government banned the Palestine Action group under anti-terror laws.
Prisoners for Palestine, which organised the protest, said in a statement that Thunberg was arrested under the UK Terrorism Act. Thunberg, 22, was holding a sign reading: "I support the Palestine Action prisoners. I oppose genocide." City of London Police said several people were arrested.
They did not directly name Thunberg, but said "a 22-year-old woman (...) has been arrested for displaying an item (in this case a placard) in support of a proscribed organization (in this case Palestine Action) contrary to Section 13 of the Terrorism Act 2000."
Police said another three people were arrested at the protest, at a building in London's financial quarter, on suspicion of criminal damage. The three were detained after "hammers and red paint were used to damage a building," and they glued themselves to fixtures nearby, police said. Prisoners for Palestine said its protest had targeted the offices of Aspen Insurance because the company provided services to Israeli-linked defence firm Elbit Systems UK.
