More than 30 firefighters were called to tackle a fire at a car repair garage on an industrial estate in Corby.
Six crews went out to the fire at one of the units in Brunel Road on the Earlstrees industrial estate in Corby, which started just after 5am this morning (Wednesday).
Group manager Ian O’Donovan from Northamptonshire Fire and Rescue Service said it took about an hour to put out the fire at unit 10, which is one of about 16 on the site.
He said the fire was contained to this unit, although there was some smoke and water damage to several of the surrounding units.
Western Power was called out after the fire to try and restore power to the site.
Police have said they are investigating the cause of the blaze, but speaking from the scene this morning, Mr Donovan said: “We are treating the fire as suspicious.”
A police spokesman said: “We were called at 5.10am to Brunel Road on the Earlstrees industrial estate to a significant fire at a car repair garage.
“The fire investigation team are still at the scene trying to establish the cause.
“In total four units were damaged on the industrial estate and two have been declared unsafe because of the fire.
“At its height 32 firefighters were on the scene tackling the blaze.
“The fire is now out and the Environment Agency is there because of oil at the scene.”
Fire crews remain at the scene, although they have started to downscale the operation.
