A group of personal mobility device (PMD) users made a nuisance of themselves as they were riding around Geylang.
A video of the riders sounding sirens and blasting loud music was posted on SG Road Vigilante's Facebook group page.
It is unclear when exactly this happened but according to the caption, it was in May.
The post added that the riders were using lights and sirens to "intimidate" other road users into giving way to them.
Stomp earlier reported on a group of around 18 PMD riders seen crossing a busy junction around a crowd of pedestrians during the Ramadan Bazaar on May 27.
