A teenager has been arrested in connection with a recent spate of fires at Ellesmere Port's old greyhound stadium.
The 15-year-old is helping police with their enquiries into the three fires, which all happened on three consecutive nights this week at the derelict building in Thornton Road.
Ellesmere Port Local Policing Unit are investigating the incidents and are urging anyone with any information relating to them, or the identity of those responsible, to come forward.
In the latest incident which happened last night (Thursday, April 14) a number of youths were seen entering the building, and local residents are being urged to report any suspicious activity to police immediately.
Detective Sergeant Rob Grantham said: "We are appealing for anyone who has witnessed any of the incidents, knows who is responsible, or has any information, which might assist with our enquiries, to get in touch. Even the smallest amount of information can be useful when piecing together a case.
"Although it may seem like harmless fun this sort of behaviour is very dangerous. Disused or derelict buildings should never be entered without permission, as they are generally a dangerous environment – add to that the fire element and it is a very worrying situation.
"Derelict or unoccupied buildings may seem like an opportunity to explore or take risks for fun − this is not the case and we would urge anyone who has been involved in this kind of activity to consider their safety and the law."
Station Manager Colin Hayes, Arson Reduction Manager at Cheshire Fire and Rescue Service, added: "We work very closely with our police colleagues in incidents such as this.
"Arson is a very serious crime, which can have a massive impact on the local community. This sort of crime is extremely dangerous and puts the lives of the public and firefighters at considerable risk. It also takes up a lot of valuable time and resources which are needed for real emergencies."
"Enquiries are ongoing and officers are actively targeting those involved in this sort of activity in the area."
And after today's arrest, DS Grantham said it was important parents knew where their children were at all times.
"We are urging parents to ensure they know where their children are and what they are up to," he said. "It is also important for parents to stress the potential dangers involved in going into derelict buildings and urge their children to stay away."
Anyone with any information is urged to call Cheshire Police on 101 quoting incident number 773 of April 14.
