Kelvin Wilson 'assault' shames club, says Derby County boss
Events including an alleged assault by a fan on a Nottingham Forest player have "brought shame" on Derby County, its chief executive has said.
Footage shows a man making contact with Kelvin Wilson after Forest beat Derby 2-1 at the iPro Stadium on Saturday.
A car belonging to Nottingham Forest chairman Fawaz Al Hasawi was also found vandalised in the directors' car park.
Sam Rush, Derby chief executive, apologised in a statement following the events on Saturday.
Mr Rush said: "The events which unfolded, following our disappointing result against our local rivals on Saturday, have brought shame on our club.
"I know that the vast majority of Derby fans are equally appalled by the callous act of a thoughtless individual seeking to attack a player on the pitch and similarly those who chose to vandalise the Forest chairman's car after the match.
"We can only apologise for those individuals who mistakenly call themselves Rams fans."
He added that he would seek to "permanently exclude" supporters guilty of any wrongdoing.
A 23-year-old Derby fan, who was originally arrested on suspicion of pitch encroachment, has been interviewed about the alleged assault and bailed.
Supt Gary Parkin, the match commander, said it was "very unfortunate" the man slipped through a line of security.
He said: "It's very difficult to try and stop everybody getting on the field.
"We have plans in place, pitch encroachment plans with Derby County but at times if you want to get on to the pitch and you're in the right part of the ground, what happens is, sometimes, they slip through... it's entirely unacceptable."
Mr Parkin said officers are currently going through CCTV to try and find those responsible for the damage to Mr Al Hasawi's car.
