At least three busloads of police officers in riot gear responded to a riot that broke out along Race Course Road around 10pm on Sunday night. The mob, believed to be made up mainly of foreign workers, apparently attacked an ambulance and a traffic police highway patrol car responding to an accident earlier in the vicinity.

The Straits Times understands that a worker was hit by a bus earlier and first responders were believed to be attending to the victim when the riot started.

At least two vehicles were set on fire. According to preliminary reports from the ground, one of the vehicles that was on fire is an ambulance. A few police cars were overturned and one was set on fire.

There were at least two explosions at the scene involving these vehicles. Police have cordoned Race Course Road, as they try to contain the situation. A section of the shops along Buffalo Road have been ordered to shutter.
