Three boys arrested over huge Sleaford straw blaze
Three boys have been arrested on suspicion of arson after a fire destroyed thousands of bales of straw near Sleaford in Lincolnshire.
The 24,000 straw bales were being stored for use at a nearby straw-fired power plant.
Fire engines remain at the scene and a section of the A15 is expected to remain closed until Monday evening.
The fire started in a field between Quarrington and Silk Willoughby at 18:00 BST on Sunday.
Two of the boys will be questioned about the fire "in due course" while the third has been questioned and released on bail, Lincolnshire Police said.
Lincolnshire Fire and Rescue advised people living nearby to keep their doors and windows closed to avoid smoke getting inside their homes.
BBC reporter Leigh Milner, who was at the scene on Monday morning, said: "A huge orange glow can be seen for miles around - a grey band of smoke is spreading across the sky and the fire is still burning furiously."
North Kesteven councillor Mark Allan said: "The straw is stockpiled and used at the straw-fired power station in Sleaford.
"The power station can't handle a large store of straw so this was the place chosen to store it.
"It is a very large stockpile of straw - I have always been concerned a large pile like that could be a fire hazard."
