Dramatic CCTV footage on social media reveals the moments a floor shearing away in a matter of seconds under the students. More than 70 people were injured after a mezzanine floor at the Indonesia Stock Exchange collapsed onto the building’s lobby on Monday, January 15.
Police blocked off the complex as panic-stricken people fled the scene. Many of the injured were university students who were on the mezzanine floor when it collapsed.
“There was a rumbling noise but it wasn’t an explosion. It was like something had fallen, and suddenly the floor we were standing on fell away,” said one student. Police ruled out a bomb attack as the cause of the collapse.
