At least 75 people were injured when a mezzanine floor of the Indonesia Stock Exchange in Jakarta collapsed earlier the same day.

Indonesian authorities have sped up investigation to find out reasons behind the collapse.

National police spokesman Inspector General Setyo Wasisto disclosed that police investigators would investigate blueprint of the building after the incident.

Every building has its own blueprint, so there must be information stipulating how long a building will remain strong, he said at the police headquarters.

The spokesman ensured that the cause of the incident is not an explosion.

Images aired on television and circulated on social media showed a concrete and metal structure that had collapsed around a Starbucks cafe near the entrance to the lobby of the building.

All victims were taken to local hospital, and investigations are underway, police said.

The high-rise building, constructed in the late 1990s, is part of a two-tower complex also housing offices of the World Bank and the International Finance Corporation.  It was the target of a car bombing by Islamist militants in September 2000.
