Police have nabbed two teenage boys who set off a home-made bomb that started a bushfire on the state's mid north coast.
Police say the boys, both aged 16, threw the home-made explosive into bushland near Crestwood Drive at Port Macquarie, on Sunday afternoon.
The bomb exploded, accidentally causing a bushfire nearby.
The boys unsuccessfully tried to put out the fire, which was later extinguished by firefighters.
No property was damaged and no one was injured.
The boys were arrested, but later released without being charged.
