Flames char 30 acres on Valley Isle

A suspicious brush fire burned 30 acres of fallow sugar cane Wednesday night in Pulehu, Maui.

The cause is undetermined but considered suspicious because fire crews saw small fires in two locations that grew into one large fire front, the Maui Fire Department said in a news release.

The fire began at 8:53 p.m. on the south side of Pulehu Road, 2 miles east of the Hawaiian Cement batching plant. It was contained by 7 a.m. Thursday.
