Jakarta. The collapse of a mezzanine floor of the Indonesia Stock Exchange, or IDX, building on Monday (15/01), which injured 77 people, was not caused by a bomb, the National Police have confirmed to the Jakarta Globe.
The injured have been admitted to the Navy Hospital, Siloam Hospital, Pertamina Hospital and Jakarta Hospital, all in the southern part of the capital city, National Police spokesman Insp. Gen. Setyo Wasito said.
Most of the victims suffered bone fractures.
Police deployed a bomb squad to comb the ruins.
"No bomb was found at the IDX complex," Setyo said in a text message.
Footage from at least two closed circuit televisions (CCTVs) at the building shows scores of people lying in the rubble, many of them were visiting students from Bina Darma University in Palembang, South Sumatra.
The accident occurred during lunch hours, a few minutes after the first trading session ended. Trading activities remained uninterrupted.
The high-rise two-tower building, constructed in the late 1990s, also houses the World Bank and the International Finance Corporation offices. In 2000, a car bomb planted by Islamist militants exploded inside its parking lot, killing 10 people.
Finance Minister Sri Mulyani Indrawati expressed her hope that the floor collapse will not affect investor confidence in Indonesia. The exchange resumed business in the afternoon as per schedule, Reuters reported.
The cause of the accident is still unknown.
