Firefighters believe a blaze in which four large vehicles were torched overnight was started "deliberately".
Cheshire Fire and Rescue Service (CFRS) said two appliances from Runcorn and one from Widnes were called to Aragon Court in Manor Park industrial estate, Runcorn, at 1.11am on Monday. A CFRS spokesperson said the "heavy goods vehicles" contained recycled white goods and appliances.
Crews used two main jets, two hose reel jets and three sets of breathing apparatus as they tackled the suspected arson. CFRS said the blaze was believed to have been started "deliberately".
