Jakarta — At least 75 people were injured on Monday when a mezzanine floor at Indonesia’s stock exchange building collapsed into the lobby, police said, with victims carried out of the debris-filled building on stretchers.

Dramatic CCTV footage showed a group of about 40 visiting students on a balcony section plunge as the floor gave way with a cascade of glass, metal and other material crashing onto the ground floor, where several others were walking.

A Jakarta police spokesperson said the collapse was an accident and not the result of an explosion.

National police spokesperson Setyo Wasisto said 75 people had been injured. There were no reports of deaths so far.

Television images showed chaotic scenes as victims were taken to hospital or lay on the ground outside the tower complex in the centre of the sprawling city’s business district.

"I saw many people bleeding," student Rizki Noviandi, who was taking part in a competition at the exchange building, told Metro TV.

"So many people were carried out of the building and were left on the grass outside … until the ambulances arrived." The lobby was filled with debris and toppled-over plants near a Starbucks coffee outlet, as hundreds of building employees were evacuated from the complex, which was bombed by Islamist militants in 2000.

At least 10 people were killed and dozens injured by a car bomb in that attack.

"Our search and rescue teams, the police, doctors, the firefighters are all still working," Wasisto said. "They are cleaning the debris and also searching for other possible injuries," he added.

Those hurt mostly sustained injuries to their legs and arms, including broken bones, a spokesperson for one local hospital said.

Jakarta police spokesperson Argo Yuwono added: "The accident happened at the first floor … it’s a floor where many employees are passing by." The collapse took place in one of two towers in the complex.

"There was a sound, like something had fallen off a building structure, for about 20 seconds. Everyone was panicking and people were immediately being evacuated," Amailia Putri Hasniawati, a journalist based at the exchange, said.

It was not immediately clear what caused the accident at the tower in Sudirman district, which was built in 1995.

"Material degradation could be the cause," construction expert Iswandi Imran told local TV.

"It could be corrosion or anything which slowly degrades the strength of the structure so it cannot take the weight any longer. But all that has to be investigated."

Despite the chaos Monday, trading continued as usual in the afternoon session with the main index closing 0.2% higher.

The accident happened shortly after noon local time (5am GMT) while the market was on its lunchtime break.

"There was a loud banging so people who were inside immediately ran outside of the building," said Metro TV journalist Marlia Zein.

The local office of the World Bank is housed on the 12th floor of the complex, according to its website.

Reports at the time of the 2000 bombing said one of the men responsible was a member of the Free Aceh Movement, a separatist group which had been fighting for a free Islamic state in Aceh province since the mid-seventies.

About 200 cars were also damaged in the blast in an underground parking lot.
