"15 ambulances had been conveying victims to hospitals"

More than 70 people were injured when a walkway at the Indonesia Stock Exchange building collapsed.

The Straits Times reports that the incident occurred on Monday at Tower 2 of the Jakarta based institution. The walkway is crossed by many people per day and links Tower 2 to Tower 1.

Whilst the cause of the collapse is unknown, police have ruled out an explosion.

Videos of the incident have circulated on social media, showing victims screaming and rushing out of the building. CCTV footage shows the walkway collapsing with people on it.

Many were trapped under the debris and were carried out on stretchers.

Jakarta police spokesman Argo Yuwono confirmed that 77 people were injured and were being treated at four hospitals. No related fatalities have been reported.

“We are still evaluating, but earlier, 15 ambulances had been conveying victims to hospitals,” he said.

After the initial chaos, many rushed back in to help carry out the injured found amid bent steel structures, broken glass and other debris of what was left of the walkway.

CIMB Private Bank economist Song Seng Wun was attending an event at the building and luckily was not in the vicinity of the accident.

“Our event just ended and the floor collapsed,” he told The Straits Times before returning to Singapore on Monday. “Luckily, all these happened just before the lunch crowd came down.”

Alpino Kianjaya, director of the stock exchanged, declined to comment on the incident.

“Trading continued as normal despite the grave incident, evidence that the disaster recovery plan set out by the bourse is working successfully,” Tito Sulistio, president director at the stock exchange said.
