The owner of a breakers yard has spoken of his shock after £50,000 of stock went up in flames.
Police have launched a probe after a blaze tore through a yard holding caravans and vehicles.
Ben Barnes said seven vehicles, three caravans and his office were destroyed in the suspected arson attack at around 4am on Wednesday.
A 100-metre exclusion zone was set up for several hours at Copy Clough Cars and Caravans in Church during the blaze.
Firefighters feared gas canisters might explode so watched from behind a cordon as stock in the yard burned.
Thirty-five firefighters fought the blaze which was finally declared safe at midday after the acetylene cylinders cooled down.
A joint fire and police probe has now been launched and they are treating it as suspicious.
Mr Barnes, 41, from Oswaldtwistle, said the Church Lane business – which buys and sells cars, caravans and accessories – will hopefully bounce back.
He said: "I’m in shock and it hasn’t hit me yet.
"My two dogs were in the yard and they are lucky to be alive after what this callous person has done.
"I now need to look towards the future and try to move on and rebuild."
A Ford Ranger pickup truck, a Vauxhall Astra, a Fiat Doblo, two Iveco trucks, a Range Rover, a Talbot Express motor caravan, a 1960 Bedford TK Truck and a Suzuki motorbike that Mr Barnes was keeping for a friend, were all destroyed in the fire.
Watch manager Phil Whittaker, of Hyndburn Fire Station, said parts of the yard became engulfed in flames at around 4am on Wednesday.
He said: "We saw on arrival that fires had been started at different points which points to it being suspicious. It’s a charred mess now.
"The main concern was to continue cooling the cylinders down until it was safe."
Mr Barnes said he has more than 50 per cent of his stock left and is still open for business.
