The Government will not tolerate such lawless behaviour," said Mr Teo, who is also Minister for Home Affairs. "I have asked Police to deal with all aspects of the incident, including the traffic accident, what happened immediately after the traffic accident, and all ensuing incidents."
Commissioner Ng said: "You can expect that we will make further arrest in the hours and the days that follow. Anyone with information about people who were involved in the violence last night should tell the police.
"We will go all out to find, to bring to custody, everyone who was involved in this incident.
