A 21-year-old man has been arrested on suspicion of assault after Sheffield Wednesday goalkeeper Chris Kirkland was hit by a fan during an npower Championship game.
The incident was one of a number of ugly scenes at Hillsborough during the 1-1 draw with Leeds United which was televised on Friday night.
Gloucestershire Police said the man was arrested in Cheltenham.
A spokesman said: "The investigation is being led by South Yorkshire Police. The man currently remains in police custody."
Kirkland, who has played for England, was shoved to the ground moments after conceding an equaliser in the 76th minute.
A hooligan ran from the Leeds fans onto the pitch and pushed Kirkland in the face, before running back into the crowd.
The incident was caught on camera by Sky Sports who were broadcasting the derby game, yet the suspect was not arrested until Sunday.
Quickly the thug was identified on social media sites with hundreds of fans joining in the condemnation. A mobile phone number was even posted, supposedly belonging to the suspect.
The Football Association said it will investigate events.
There were five arrests for various offences including public order before and after the game, while three people were ejected from the ground and 12 were subject to dispersal orders.
