The plight of Metford sisters Kathryn Blakemore and Linda Carter whose cars were torched last week and caused them to flee their home, has prompted Metford Neighbourhood Watch (NHW) officials to install CCTV at their home.
At 5am last Monday, neighbours alerted the sisters, who also live with Kathryn's 20-year-old disabled son, to the fire and told them to evacuate their house immediately.
There were concerns the building could also catch fire.
A wheelie bin had been placed between the sisters' cars and set alight, spreading to the carport and dangerously close to their home.
NSW NHW President Bill Hackney, said the terrible damage done to their cars was unacceptable in any community.
"Metford NHW Facebook page is asking the surrounding houses for any CCTV evidence to put forward to the investigation," Mr Hackney said.
"It was disturbing that a second attempt was made whether the two incidents were committed by the same person is unknown.
"NHW will be assisting Kathryn with a Metford NHW Liam CCTV loan camera unit to hopefully monitor any further incidents and also hopefully give the victims some peace of mind.
"We are calling on anyone that have any information to call Crimestoppers," Mr Hackney said.
Neither Linda or Kathryn's cars were insured.
"We are at a loss to understand why this happened. We have no enemies.
"Now we're frightened, we can't sleep and have no transport," Linda said.
Linda's Mazda 3 which has travelled only 78,000 kilometres, is beyond repair and damage to Kathryn's Toyota Corolla is currently being assessed.
