The trouble started after a private bus fatally knocked down an Indian pedestrian, 33-year-old Sakthivel Kuaravelu in Little India.
Some 400 migrant workers were involved in the rampage that left 39 police and civil defence staff injured and 25 vehicles—including 16 police cars—damaged.
Singapore previously witnessed violence of such scale during race riots in 1969.
Presently, 25 Indians face one rioting charge each, punishable by up to seven years in prison and caning.
The court offered bail to the remaining 25 Indians after submitting sureties of 20,000 Singapore dollars with one guarantor or 10,000 Singapore dollars with two guarantors each, Attorney General's Chambers spokesperson told PTI.
