Vandals have been blamed for causing “extensive criminal damage” to Deepdale, the home of famous English football club Preston North End.
Several deliberate fires have been caused at the northwest venue in recent weeks, the club said in a statement.
The club, which plays in the second-tier Championship, said that it had been the “victim of a number of incidents” recently, with staff also threatened.
There are fears of a major safety risk if one of the fires takes hold properly.
The club's safety officer, Mark Farnworth, urged anyone with information to contact him or the police, who are investigating the incidents.
“We are working closely with the police to identify those involved to ensure that they are prosecuted to the full extent,” he said.
“If required, the club will seek to sue individuals for civil trespass and obtain court injunctions to keep them off Preston North End property.
“It's your club and we need your help to stop this anti-social behaviour.”
