Teens charged over suspicious NSW fires

Three teenagers have been charged after three properties were set alight on NSW's north coast.

One fire caused minor damage to an abandoned building in Port Macquarie in May. The second fire in an abandoned duplex was set alight in August and in the third a house was set alight, police say.

The males - aged 16, 17 and 18 - were charged with aggravated break and enter and destroying property in company by fire.

The 16 and 17-year-olds will face Children's Court on November 16 and the 18-year-old is scheduled to appear at Port Macquarie Local Court on October 11.
