Mr Adams, accompanied by party manager Adam Walker and a small group of activists, attended the Millgate Arts Centre in Oldham, which was scheduled to start at 2.30 pm.
“Mr Adams had booked into the hustings and had tickets for himself and the team,” Clive Jefferson, British National Party national organiser reported.
“Mr Adams and his team went as planned and they were allowed entry without any trouble at all.
“Everything appeared to be going normally and the venue was full with a large media contingent present,” Mr Jefferson said.
“It was then that a Labour Councillor told Mr Adams he could not sit with the other candidates and that he had to leave,” Mr Jefferson continued.
“Mr Adams is not a man to be bullied or ordered about during his election campaign by anyone, and certainly not the Labour Party.
“He quite rightly told the Labour lackey that he was a candidate in the by-election, this was a hustings and he was going nowhere.”
The hustings start was then held up as the Labour councillor called the police who then told Mr Adams that the "event organiser" wanted him to leave.
“Mr Adams very calmly said that he was not prepared to leave just because the Labour Party objected, and said that it was an ‘absolute outrage.’
“The police officer then went outside and came back with six of his colleagues. They surrounded Mr Adams, physically dragged him from his seat and marched him out,” Mr Jefferson said.
Mr Walker then stood up and told the hustings crowd that “democracy is clearly dead in Oldham.
“If they wanted more paedophile gangs of Muslims preying on our children in Oldham all they had to do was keep voting for the likes of those politicians left on the stage,” Mr Walker said, before leading a walkout of the party’s supporters in the crowd.
