Maui police and the Federal Bureau of Investigation are investigating a suspected improvised explosive device that detonated and damaged a car that was driving in Pukalani last night, according to multiple sources.

At about 9 p.m. Thursday night Maui firefighters and police closed Old Haleakala Highway in both directions up to Makani Road after responding to multiple reports of a loud explosion and a motor vehicle accident.

According to the Maui 24/7 Facebook page, witnesses said “a vehicle was driving up Old Haleakala Hwy. when the driver saw an explosion on the road on the driver’s side of her car. The explosion shattered her windows and ripped holes in the driver’s side of her vehicle.”

The woman’s car was near Ikea Place in Pukalani when it was allegedly hit by the IED.

The highway was closed from about 9 p.m. until 4 a.m. today.

Leilani Fagan posted on Maui 24/7’s Facebook page that her house “shook it sounded like there was an explosion underneath.”

“I looked and didn’t see anything but saw my neighbors running down the road. I followed and at the beginning of IKEA [Place] there was a white SUV blocking the entrance to the road. It was riddled with gouges and puncture marks on the side and her windows were broken. The driver said it was not a car accident. She thought it was an explosion and needless to say she was very shook up and scared. She is lucky to have minor injuries. The police and firemen showed up a few minutes later and closed the Section of old Haleakala Highway and IKEA. They’re taking the vehicle as part of the ‘crime’ scene and examining the concrete and debris all over the road where the explosion took place. There is a suspicion that it’s a pipe bomb however this is not confirmed until further investigation!!” read her post at about midnight.

Maui police and the FBI said they are investigating.
