Eight other people remain in custody, Staffordshire Police said
A man has been charged after a two-day protest at a factory that produces engines for drone aircraft.
Nine members of the London Palestine Action group climbed on to the roof of UAV Engines Ltd in Shenstone, Staffordshire, at 05:00 BST on Tuesday, closing the plant.
They were protesting against UK arms sales to Israel.
A 29-year-old man from Islington has been charged with aggravated trespass, while eight others remain in custody.
The man has been bailed to appear before magistrates in Cannock on 20 August, with a condition not to enter Staffordshire in the meantime.
The eight others – three men and five women – are being questioned on suspicion of aggravated trespass.
All nine had been removed from the factory by 20:30 on Wednesday, Staffordshire Police said.
London Palestine Action said protesters were also campaigning against Israel’s military action in Gaza.
Lynn Lane in Shenstone was closed during the protest, but has since reopened.
