LONDON: Half of the protesters arrested in London on Saturday in relation to the banned group Palestine Action are older than 60, police data shows.

Officers arrested 532 people at the mass demonstration against the proscription of Palestine Action as a terrorist organization last month, The Guardian reported.

All except 10 were arrested under Section 13 of the UK’s Terrorism Act for displaying placards or signs in support of a banned group.

London’s Metropolitan Police on Sunday released an age breakdown of the people arrested at the demonstration. Almost 100 were in their 70s and 15 were aged 80 or older.

The event was organized in Parliament Square by Defend Our Juries, which requested that protesters hold signs saying: “I oppose genocide. I support Palestine Action.”
