According to Colin Leyland, the vice-chairman of Worcester City Football Club, there were a 'few idiots' amongst the Hereford United support when the two clubs played each other in a pre-season friendly last Saturday at St George's Lane.
The game was held up during the first half by the referee.
"A few idiots were there to cause trouble, not watch the football," Leyland told the Worcester News.
"Some damage was caused to the hordings and the referee had to stop the game because they were on the pitch.
"It was supposed to be a friendly match so it's a shame it happened. Thankfully the second half was peaceful."
According to the paper police ejected 'several away fans' and one was arrested after a steward was punched in the face.
