The chief executive of non-league Mansfield was arrested during a match.
Carolyn Still, 29, was held for using threatening words and behaviour during Mansfield Town's Blue Square Bet Premier play-off semi-final against York City on Wednesday night.
It is understood she received a caution for her behaviour in Grosvenor Terrace, next to York's Bootham Crescent stadium.
A spokesman for North Yorkshire Police said: 'A 29-year-old woman from Retford was arrested at 9pm on Wednesday 2 May 2012, on Grosvenor Terrace, York, for using threatening words and behaviour. She was given an adult caution before being released.'
During the eventful game Mansfield, who had a player sent off, survived to hold York to a 1-1 draw.
Mansfield Town have declined to comment.
