Police looking into video of guy chanting '369' during K-pop girl group Twice's concert

Police are looking into a video in which a concertgoer can be heard chanting a gang slogan during K-pop girl group Twice's concert on Sunday (June 17).

The seven-second video appeared to have been originally posted by a Twitter user, and shows a voice shouting "sah lak kau" (meaning '369' in Hokkien) during the event.

The slogan is synonymous with the gang Sio Kun Tong.

"HAHAHAHA MY BROTHER WENT TO THE TWICE CONCERT IN SINGAPORE BUT HE [DON'T KNOW] THE CHEER SO LISTEN TO WHAT HE SAID INSTEAD," said the Twitter user.

A screenshot of the tweet was also posted on Sure Boh Singapore's website:

In response to a Stomp query, the police said they "are aware of this incident and are looking into the matter."

The three-hour concert at the Singapore Indoor Stadium saw the nine-member group performing to a crowd of around 8,500 fans.
