helicopter crash inside an industrial park in Morowali, Central Sulawesi, left one man dead on Friday, local authorities say.

The helicopter belonging to PT Indonesia Morowali Industrial Park (IMIP) crashed at around 9:30 a.m. near a helipad inside the Morowali Industrial Park. The helicopter was due to take six Chinese citizens to Halu Uleo Airport in Southeast Sulawesi’s provincial capital of Kendari, according to a company spokesman.

The helicopter had been in the air for around five minutes when the crew decided to return to the industrial park. It suddenly descended 100 meters near the helipad.

Morowali Police reported on Friday that an IMIP worker named Aris Heni Irawan, 23, had died after being hit by the crashing helicopter.

Four of the Chinese citizens were in Morowali to interview IMIP employees, while the other two were foreign workers of the company, its spokesman Dedy Kurniawan told a press conference.

“The four Chinese nationals planned to return to China, so the company was taking them to Kendari first,” said Dedy.

The six Chinese citizens were identified as Guan Kejang, Zhao Yipu, Du Gui, Xi Lai Wang, Yan Yun and Di Yi Fei.

The two crew members, pilot Rudi A. and copilot Deliati Hasiholan Gulo, suffered severe injuries.

Dedy said the crash was being investigated by the National Safety Transportation Commission (KNKT).
