Mumbaikars complained of a strange odour on Thursday, with the BMC's disaster cell receiving 29 complaints from all over the suburbs. The authorities, however, have said they were unable to trace the source despite looking for it for hours.

Social media was immediately abuzz late Thursday night owing to this mystery odour. Nine teams of the fire brigade were on their toes all of Thursday night, but none could find where it had started from. While citizens slammed the fire department's inability to find out the source of the odour, some said the smell disappeared after a while, whereas others turned off piped gas connections as a precautionary measure. Mahanagar Gas Limited, too, was on field to detect any leak, but found nothing.
