Floor Collapses at Indonesia Stock Exchange Building

JANUARY 15, 2018

At least 77 people were injured when a mezzanine floor at the Indonesia Stock Exchange, or IDX, collapsed onto the building's lobby on Monday (15/01).

The accident occurred during lunchtime, a few minutes after the first trading session ended. Trading activities were uninterrupted.

The injured, most of whom had suffered bone fractures, were taken to the Navy Hospital, Siloam Hospital, Pertamina Hospital and Jakarta Hospital, all in the southern part of the capital, National Police spokesman Insp. Gen. Setyo Wasito said.

Many of the injured were visiting students from Bina Darma University in Palembang, South Sumatra.

While the cause of the accident is still unknown, there is speculation that the floor may have been overloaded.

The building was the target of a suicide bombing by Islamist militants in September 2000, but police have ruled out a bomb as the cause of Monday's collapse.

"No bomb was found at the IDX complex," Setyo said in a text message.

The high-rise two-tower building, constructed in the late 1990s, also houses the offices of the World Bank and International Finance Corporation.
