THIS is the horrifying moment a "bully" arsonist set fire to his neighbours' home as their autistic sons slept inside.
Isaac Brooks, 42, squirted petrol through a tumble dryer vent and torched Bev and Dave Beavers's house in Bolton, Greater Manchester after launching an anti-disabled rant.
Dave, 46, rescued his stepsons Adam, 25, and Chris Kelly, 27, and Bev after going downstairs and finding flames ripping through the kitchen.
Drug-crazed Brooks had cut the family's CCTV wires and was later heard singing "burn baby burn, disco inferno."
He had shouted at the family: "You f*****g inbreds, I'm going to burn the lot of you."
Bev, 54, told Manchester Evening News: "I have lived here for 25 years. It was a quiet close with lovely neighbours and no problems.
"Our boys became too scared to set foot outside the door."
She added: "They have Fragile X syndrome, which a severe form of autism with learning delays. They simply cannot cope with individuals like Brooks."
Residents had previously complained to the police and council after Brooks played loud music all night and threatened locals.
Bev ended up on anti-depressants and was unable to sleep after living next to the neighbour from hell, who targeted her disabled sons.
She said: "We were being bullied in our own homes and there was nothing we could do about it.
"We felt powerless.
"We couldn’t close the curtains for fear of something dreadful happening. Then the fire happened, and all our fears became a reality.”
The blaze destroyed around £30,000-worth of the family's belongings and they had to move out as repairs were carried out.
It was initially though a faulty tumble dryer caused the inferno, but the family became suspicious when they found their CCTV wires had been cut.
Forensic investigators retrieved the footage, which showed Brooks setting fire to the property then fleeing.
Bev added: "I noticed the CCTV wires had been cut.
The fire happened, and all our fears became a realityBev
"I knew it was Brooks. I had an instinct and I was right."
A few days after setting fire to the family's home, Brooks was heard singing 'burn baby burn, disco inferno', Bolton Crown Court heard last week.
He had 37 convictions for more than 80 offences, the court heard.
Caging him for ten years, Judge Martin Walsh warned Brooks he posed a "significant risk of harm" to the public.
Sentencing him, Judge Walsh said: "This was a serious intended arson attack upon an innocent family who were fast asleep at their home address.
