A 12-year-old girl has been charged with setting fire to her home on the NSW central coast.
Firefighters were called to the property on the Central Coast Highway at Erina at 1am on Saturday where they found a house well alight.
Crews extinguished the blaze, but it caused extensive damage, police said.
Two 12-year-old girls were arrested at the house by police a short time later.
One of the girls was charged with causing more than $15,000 worth of damage to property by fire and will appear in a Children's Court on Saturday. The other girl was released without charge.
Police said no one was injured in the incident.
