Westmeath County Board is investigating claims that stones were thrown at a linesman during last night's Leinster U21 football championship quarter-final between Westmeath and Wexford.
It has been alleged that top Longford referee Derek Fahy, who was on the line for the match at Mullingar's Lakepoint Park, was hit by stones as he consulted with referee, Fergal Barry prior to the sending off of Westmeath's Kelvin Reilly in extra time.
Westmeath lost the quarter-final by virtue of a late goal by Wexford's Robert Dempsey.
County board chairman, Sean Sheridan said that reports by eyewitnesses have been taken on board, and a full investigation is under way.
"Behaviour of that sort won't be tolerated at all," Mr Sheridan said.
