The fire brigade and the disaster management helpline received multiple complaints of a gas leak from areas in the eastern suburbs. But despite inspections, fire officials said that they were unable to identify the source of the suspected leak.

One of the complaints came in from the area around the US Vitamin Company in Govandi East. "After the complaint, 13 fire engines were sent to the spot. We have called and informed HPCL, BPCL RCF MGL, as well as the police about the leakage and the companies, have been asked to check their premises. The source of the leakage, however, could not be detected," said a civic official.
