Five people were injured in an incident at Enterprise Centre located at 20 Bukit Batok Crescent today (Sept 11) at around 11am.
Stomp contributor Judy, who was working in the building, reported hearing a loud sound and went to investigate.
She told Stomp in a telephone interview: "I heard an explosion from a neighbouring unit. It was very loud."
Parts of a ceiling and a wall were severely damaged in the incident.
In a photo the Stomp contributor sent, debris can be seen strewn all over a stationary car.
Judy added that around two to three people were injured but they were conscious.
When she was at the scene, paramedics had arrived and were attending to the victims.
The Stomp contributor, as well as other onlookers, were then told to evacuate the area.
The Singapore Civil Defence Force (SCDF) said in a Facebook post this afternoon:
"There was no fire upon SCDF arrival. The industrial incident resulted in the partial collapse of a wall and significant damage within the premises. No one was trapped in the incident."
SCDF added that the injured workers have been taken to hospitals and investigations are ongoing.
Another Stomp contributor, Raymond, told Stomp that he had intended to drive into the road outside Enterprise Centre at around 11.50am, but discovered that it had been blocked by the police.
He reported seeing police cars and fire engines in the vicinity of the building.
While having lunch at a nearby eatery, Raymond said he heard passersby saying that there was an explosion at the industrial area.
