A Derby supporter has been arrested after running onto the pitch after Saturday's game against Nottingham Forest and making contact with a Forest player.
The incident came at the end of the Sky Bet Championship match at the iPro stadium, which Forest won 2-1.
Witnesses saw a supporter run on after the final whistle and swing at Forest defender Kelvin Wilson, before confronting a handful of other visiting players.
The fan, who ran on from a Derby section of the stadium and through a line of stewards, appeared to swing at Wilson and was then tackled to the ground by Forest defender Jamaal Lascelles.
He was surrounded by stewards and dragged away from the Forest players.
A police spokesman said: "Tension arose between both sets of supporters towards the end of the game, after Nottingham Forest had scored their second goal.
"A 23-year-old Derby supporter from the south stand entered the playing area and made contact with a Nottingham Forest player.
"The supporter has been arrested, and a joint investigation will be taking place between Derbyshire Police and Derby County."
There was also trouble off the pitch, as Forest chairman Fawaz Al-Hasawi tweeted pictures of his vandalised car.
Alongside the images, showing a missing number plate and damaged wheels, he posted: "Very professional! But in the end I don't mind at all! The 3 points are more important!"
