A football fan has been given a 10-month prison sentence following post-match clashes in which brooms and mops were hurled at police.
The trouble flared up after a non-league match between Luton Town and York City on May 3.
Anders Johansen, 37, from Drobak, Norway, pleaded guilty to a public order offence earlier this month.
He was jailed for one count of violent disorder at Luton Crown Court yesterday, a court official said.
Luton supporters invaded the pitch following their team's 1-0 defeat by York in the Blue Square Premier League semi-final play-off, Bedfordshire Police said.
Missiles including coins were thrown at York's players and riot police were called in after the game at the Hatters' home ground, Kenilworth Road.
Stewards and police had to help York's players escape to the dressing rooms, via the away end.
The violence spilled over to nearby Dunstable Road, where a small number of fans attacked police with mops and brooms they found outside a DIY store.
Six other people, who were arrested on suspicion of public order and drunk and disorderly offences, were released on bail pending further inquiries.
No fans were believed to be seriously hurt in the incident but a number of police officers received minor injuries.
