A 28-year-old has been arrested and bailed in relation to protest marches in Peterborough.
The English Defence League (EDL), which says it opposes Islamic extremism, Unite Against Fascism and the TUC, demonstrated on 11 December.
The man, from Nottingham, was arrested over the offence of intentionally causing religiously-aggravated harassment, alarm or distress. He has been bailed to return to police in Cambridgeshire in February.
