STOMPers said many people in Shenton Way thought a building had collapsed and called the SCDF when they felt tremors and heard loud rumbling sounds at about 12.30pm today (12 Oct).

Civil Defence officers helped in the search for a worker feared trapped in the debris of the building being demolished.

Another STOMPer, who wanted to remain anonymous, sent a video and photos of the scene at about 3pm, outside Asia Chambers Building.

"Before we went for lunch at about 12.30pm, we felt slight tremors," she said.

"The guy at the convenience store next to the building said he heard a loud bang. I heard that one part of the building inside had given way.

"The road around the building was cordoned off and there were fire engines and ambulance."

STOMP contacted the Singapore Civil Defence Force, which said it received calls, reporting dust and loud sounds from the building.

"The first call came at about 12.20pm," a spokesman said.

"We would like to assure the public that no building collapsed. There was demolition work going on and there was alot of falling debris.

"Our officers were at the scene to ensure that people were not alarmed," the spokesman said.

"SCDF is assisting in the search for an unaccounted for worker which the company says might be in the debris.

"SCDF is taking no chances and is assisting in the search," the spokesman said.

STOMP contacted the Police, which said it received a call about an "industrial accident" at 12.20pm.
