Five arrests have been made following an outbreak of disorder after an English Defence League demonstration in Rotherham town centre.
Hundreds of EDL supporters gathered for the event and there were counter protests including one by Unite Against Fascism on the same day.
A fight at the Howard Public House in Sheffield later that day - September, May 10 - has been linked to the two rival groups.
Police made five arrests yesterday.
A South Yorkshire Police spokeswoman said: “Five people were arrested on suspicion of violent disorder.
“A man and two women from Unite Against Fascism and a man and a woman from the English Defence League are currently being questioned by police.
“They are all from the Sheffield and Long Eaton areas.”
