The ceiling inside a KFC restaurant collapsed - sending torrents of water into a shopping mall.

Footage captured by Gurmit Singh Kullar shows the murky brown deluge flooding part of City Square Mall in Singapore.

Water can be seen gushing from the collapsed ceiling and flowing into the hallway on the evening of September 3.

Locals stood nearby watching as the gush flooded the area, while others walked away.

Gurmit said: 'I was leaving the supermarket when the fire alarm went off and some shutters started coming down. Then a loud whoosh sound nearby.'

A mall spokesman said: 'Within minutes, the operations and security teams began redirecting traffic from the affected area while the cleaning team was activated to begin clearing the affected area.

'Our operations team deployed to the area identified the source to be a dislodged sprinkler pipe, and the related pump was promptly deactivated.'

Authorities said the flooding also reached the underpass leading to Farrer Park MRT station.

SBS Transit spokesman Grace Wu said: 'Our train service and station operations were not affected except for an escalator that was shut down as a safety precaution.'

The cause of the burst pipe is still under investigation as repair works continue.
