Fire crews believe a fire at a derelict Ellesmere Por t school was started deliberately.
Smoke was spotted pouring out of the building on Mill Lane just after 7pm last night (Tuesday, May 24) and crews were initially concerned that people were in the building.
However, when they arrived with breathing apparatus and large fans to tackle the fire and made a search of the building, they discovered nobody was on the premises.
Cheshire Fire and Rescue say they believe the fire was started on purpose and are keen to uncover any information that could help find those responsible.
