Residents have spoken of their fear after an arson attack saw flames rip through back yards destroying fences and sheds.
The fire was started at the back of properties in Leighton, Orton Malborne, at about 3am on Saturday, February 7.
Firefighters managed to bring the flames under control as the blaze was just yards from family homes where young children slept.
The fire was also a short distance away from Leighton Primary School.
One resident, who asked not to be named, said: “It was a very big fire.
“You could see and hear splinters of wood spitting out of it.
“It was very scary.’’
Another man who lives in Leighton said: “I woke up in the middle of the night and there was an orange glow in the bedroom. “I could see the fence was on fire and it had spread to a shed.
“The back windows were damaged. The outside bit had blown out, and I was waiting for the inside bits to blow as well - but that never happened.
“I was worried for my children who were upstairs, but fortunately it doesn’t seem to have affected them that much.
“The fire service managed to put the fire out very quickly - in about 20-30 minutes.
“Luckily everyone is OK.
“We stayed inside while it was going on.”
The wreckage caused by the blaze was taped off by detectives for a number of days while they conducted their investigations, and the scene was made safe.
Fire crews were at the scene for more than 90 minutes bringing the inferno under control.
Now police are trying to trace the man who is behind the dangerous arson attack.
He is described as being white, 19 to 21, 5ft 8 inches to 5ft 9 inches, slim, wearing a baseball cap, white Adidas tracksuit jacket with the word Adidas across the chest in either red or black writing. The front right hand pocket of the jacket was ripped and hanging off.
He was wearing black or grey baggy tracksuit bottoms which were tucked into white socks. He was wearing white trainers.
