Sheffield United board condemn fans' behaviour during Norwich defeat
Sheffield United's board have condemned the trouble that flared at the 1-0 home loss to Norwich on Saturday.
A statement from the Blades on Tuesday said incidents during and after the game had seen supporters injured, objects thrown on the pitch and "high-profile Norwich officials threatened and abused."
The South Yorkshire outfit have been reported to the Football Association following the Championship match and could face sanctions, including financial penalties.
The club, who face derby rivals Sheffield Wednesday at Hillsborough on Sunday, have banned seven individuals so far this season, including two from the Norwich fixture.
There was also trouble involving Sheffield United supporters at the match away against Middlesbrough last month.
Tuesday's statement featured a message from the board, which said: "We simply will not tolerate the unsportsmanlike and illegal conduct of a few to spoil things for the large majority who come along to simply watch and enjoy a football game on a Saturday afternoon.
"At Bramall Lane family values are paramount. Violence in any form is unacceptable at Bramall Lane.
"The club invests significant sums and management time in assuring the safety of our fans and guests and we shall redouble our efforts.
"We'd like to assure our fans and supporters that the staff and management of Sheffield United, in co-operation with South Yorkshire Police, will make every effort to assure a safe environment for the derby at the weekend.
"We are working with the police in coordinating a root and branch approach to identify those supporters who are tarnishing the name of Sheffield United and putting football in a very poor light.
"We want this element removed from our support so if that means other fans reporting incidents of unacceptable behaviour then let us know.
"We will issue life bans and impose other tough measures to deal with these fans."
The statement added that Sheffield United are "continuing to work with Cleveland Police following the August fixture at Middlesbrough."
