A video of the 2am incident, which has gone viral, showed several people on the pickup truck burning flares and waving a banner with the text “6.6”, and two people on scrambler motorcycles riding in circles around the vehicle.

Dang Wangi police chief Sazalee Adam said seven to eight people were believed to have been involved in the incident, and police were tracing the owners of the pickup truck and motorcycles, Berita Harian reported.

He said the group had disturbed the peace and threatened the safety of pedestrians, traders and tourists in the area.

Sazalee said police had checked CCTV footage in the area, but needed more information as all the vehicles did not have number plates.

He said police were also trying to establish the significance of “6.6” on the banner.

“We suspect a clothing shop in Dengkil is connected to the video. They will be called in to assist in the investigation,” he said.

The case is being investigated under Section 290 of the Penal Code for public nuisance, Section 14 of the Minor Offences Act 1955 for insulting behaviour with intent to breach the peace, Section 233 of the Communications and Multimedia Act 1998 for improper use of network facilities, and Section 42 of the Road Transport Act 1987 for reckless and dangerous driving.
