Maui fire and police officials are investigating two suspicious fires at condominium and apartment complexes Saturday night in Kihei.

"These fires are suspected to be related and intentionally set," Fire Department Battalion Chief Frank Tam said.

No one was injured in the fires, which caused $75,000 in estimated damage to the buildings and their contents, Tam said.

The first fire was reported just before 9 p.m. at the Southpointe condominium and apartment complex at 482 Kenolio Road. Tam said neighbors had the fire under control in about 20 minutes.

The second fire, at an apartment at 160 Keonekai Road in the Keonekai Villages complex, was reported about 10 minutes after the first fire was deemed under control by firefighters, Tam said. It took them about 15 minutes to knock the flames down, he said.

Police on Sunday did not say whether authorities had made any arrests or if they had a suspect.

Meanwhile, the fires remain under investigation by the fire department, Tam said.

The owners of both apartments were displaced but are staying with friends, Tam said.

Firefighters from the Kihei, Kahului and Wailea fire stations responded to the blazes.
