HONOLULU (HawaiiNewsNow) - The state has opened a criminal investigation into the cause of a brush fire that broke out Wednesday morning at Waahila Ridge Park.
The state Department of Land and Natural Resources said the fire was fully contained late Wednesday night, but the park will remain closed so crews can mop up the activity.
It started about 4:30 a.m., and smoke was visible throughout much of the day. Some residents reported seeing a flareup in the evening.
The Honolulu Fire Department said the fire was in a tough spot because of the thick pine needles on the ground and difficult terrain.
No damage or injuries were immediately reported.
