POLICE have vowed to track down the thugs involved in violence at the Sheffield Wednesday and Leeds derby.
Seats and advertising hoardings were ripped off by Leeds fans and thrown on to the pitch.
Other missiles were also thrown at players and stewards from the terraces.
South Yorkshire Police also confirmed there were some ‘minor scuffles’ before the game between rival fans on their way to the match.
Five arrests were made on the night and 15 dispersal orders were issued to fans deemed at risk of becoming embroiled in trouble, banning them from the Hillsborough area for a set amount of time until the game was over and the rest of the supporters had left the area.
Detective Inspector Mark Monteiro, of South Yorkshire Police, said: “We will continue to investigate other claims of disorder around Friday’s match.
“We are working with all our partners including the football clubs to quickly identify and bring to justice all the individuals involved.”
The warning comes after Leeds fan Aaron Cawley was jailed for 16 weeks after admitting assaulting Wednesday goalkeeper Chris Kirkland.
Det Insp Monteiro said: “I would like to thank the members of the public who contacted us on Friday shortly after the assault occurred.
“This incident received a lot of public and media attention and without the public’s help we may not have got such a quick verdict.
“We do not tolerate football violence of any sort and we welcome today’s verdict and are pleased to say such incidents are a rarity.”
Cawley, who has also been given a six year Football Banning Order, ran on to the pitch and slapped the goalie’s face with both hands after Leeds equalised in the second half.
He told police he had downed several cans of lager, three quarters of a litre of Vodka and six or seven pints of cider before the game.
