English Defence League founder Tommy Robinson has reportedly been arrested for breach of the peace while filming outside a courthouse.
The right-wing activist was arrested outside Leeds Crown Court and is currently being detained.
Mr Robinson, 35, is seen being led towards the back of a police van and searched in footage posted on his Facebook page.
He says: "I'm being arrested for breach of the peace."
He asks one supporter as he is led away: "Can you get me a solicitor? I'm on a suspended sentence, you see."
One officer in the footage says before reading Robinson his rights: "You are being arrested on suspicion of causing a breach of the peace."
Robinson founded the English Defence League in Luton in 2009 before resigning in 2013.
The organisation was responsible for violent marches on the streets where members clashed with police and counter-demonstrators.
West Yorkshire Police refused to comment on Mr Robinson's arrest.
