The founder of the English Defence League has been convicted of leading a brawl involving 100 football fans.
Stephen Lennon, 28, led Luton Town supporters and chanted "EDL till I die"" as they clashed with Newport County fans in Luton, a court heard.
He was charged with using threatening, abusive or insulting behaviour during the clash on 24 August last year.
He denied the charges but was convicted after a trial on Monday at Luton and South Bedfordshire Magistrates' Court.
Lennon, of Luton, was arrested by officers who told him he was being taken into custody for suspected actual bodily harm from an outstanding allegation, which was later discontinued.
The court heard Lennon, of Luton, was "egging on" and "upping the ante" as the two sets of fans fought.
Magistrates were told he had been at the front of the group of Luton fans and gesticulated "come on then" at his opponents.
Timothy North, prosecuting, said two groups of opposing fans appeared close to Luton Town's Kenilworth Road ground five minutes before the evening kick-off.
"Officers noticed the presence of Mr Lennon in the group, at the head of the Luton Town supporters," he said.
"The impression was he was egging them on and leading them on. At one stage he was alleged to have shouted the words 'EDL'."
Mr North said "there would have been a substantial degree of fighting" if police had not intervened.
However, a brawl involving about 100 fans did erupt, with only seven officers between them.
PC Robert Field, who was an acting sergeant in charge of six colleagues, said the officers wielded their batons in a bid to stop the men fighting.
He described the situation as "incredibly intimidating" to the public and said it was "clearly going to get out of control".
He said he recognised Mr Lennon because of previous dealings with him and because he had tried to arrest him earlier that day over another matter.
PC Field said: "He was a prominent person at the front of the group, giving a 'come on then' gesture."
He added: "I could see he was being looked at; he was holding the line of the Luton fans.
"He was being looked at to say: 'Do we go now?'."
District Judge Carolyn Mellanby told Lennon: "I am entirely satisfied you were at the front of this group of angry Luton supporters looking for trouble when you were confronted by the group of Newport supporters who were also angry and fired up looking for trouble.
"In DC Wheeler's words (officer in the case) you were pumped up and that's exactly how I find you would have been that day."
Lennon, who has previous convictions for assault, possession of cocaine and disorderly behaviour, shook his head upon hearing the verdict.
