A fire bug is on the run in North Beach.
The arsonist managed to evade detection after lighting a series of brush fires in the Star Swamp Bushland Preserve.
They struck five times in July and, so far this month, they have started five more fires, endangering neighboring homes and families.
Police have listed the series of times, dates and locations and have requested the upload of any CCTV, cell phone or dash camera view.
Most affected were in the North Beach Road and Charles Riley Road area, with reports at 3:05 a.m. on July 24, 8:35 p.m. on August 2, 2:25 p.m. on August 11 and 5:35 a.m. on August 18.
