INTRUDERS broke into Broadway Leisure Centre earlier this month.
Police say the offence occurred between 4pm on September 2 and 7.45am on September 5.
Although a section of stolen electrical cable was later recovered from the centre’s grounds, officers still want witnesses to come forward.
Inspector Debbie Rayment said: “This is clearly unacceptable behaviour. We will act on all information we receive to bring those responsible to justice.” Witnesses can call Crimestoppers on 0800 555 111.
