Honolulu firefighters were extinguishing a grease trap fire this morning at a Ko Olina eatery.

Honolulu Fire Capt. Michael Jones said firefighters were dispatched at about 10 a.m. to 92-1083 Olani St. and found the fire at Monkeypod Kitchen, a first-floor restaurant in a two-story commercial building.

The fire caused a large amount of smoke to exit from a roof vent, prompting building management to evacuate the property, Jones said.

Firefighters doused the smoldering grease with water and were still mopping up around noon. No one was hurt.
