Two people have been arrested after police swooped on a launch event for a group calling itself the Anti-Zionist Movement.
A 35-year-old woman was stopped in a car as she travelled to the meeting in Birmingham on Sunday afternoon and arrested on suspicion of inciting racial hatred.
West Midlands Police said the woman, from London, was wanted by the Metropolitan Police on suspicion of a public order offence as part of an investigation into speeches and social media posts.
Later, a 42-year-old man was arrested after a member of the public said she had been threatened outside the venue in Balsall Heath.
