Trouble flared following an English Defence League (EDL) demonstration in Cleckheaton, West Yorkshire, which left a man injured and damage caused, police said yesterday.
Officers are also appealing for information about a series of incidents in parts of Kirklees that followed an EDL demonstration on Saturday.
About 60 members of the EDL took part in a peaceful, pre-planned demonstration in Cleckheaton town centre. Officers had been notified about the demonstration which itself ended without incident at 3pm when the group dispersed.
However, shortly afterwards the police had to respond to reports that the window of the Co-Op in Heckmondwike had been smashed.
Two men from Bradford, a 32-year-old and a 20-year-old, were arrested and are now on bail pending further inquiries.
Officers then received reports of disorder in Dewsbury town centre at 4pm. A group of men in Corporation Street, near Pizza Go-Go, had abused and assaulted a 35-year-old Asian man, knocking him to the ground and leaving him with a black eye and bruising to his ribs. He was taken to hospital and released the next day.
The group then moved onto Northgate and Westgate.
Superintendent David Lunn of Kirklees police said: “We know that following the demonstration in Cleckheaton a number of men, purporting to be members of the EDL turned up at various location across Kirklees, displaying posters and flags and shouting abuse at members of the public. We have had a shop front damaged in Heckmondwike and the serious incident of the assault on the 35-year-old man in Dewsbury Town centre.
“These incidents cause fear and concern for innocent members of the public caught up in them and the police simply will not tolerate such behaviour.
“If people have mobile phone footage of racist chanting, damage, or assaults taking place anywhere in Kirklees on Saturday, I would appeal for those people to contact us.”
