Indian nationals Moorthy Kabildev and Mongan Anbalagan became the third and fourth men to plead guilty to rioting in Little India on Dec 8 last year.
Kabildev, 25, initially faced two charges: one for rioting, and one for causing hurt by allegedly punching bus time-keeper Wong Geck Woon.
He pleaded guilty to the former, and the prosecution withdrew the other charge, said Deputy Public Prosecutor Sarah Ong.
Kabildev was sentenced to 24 months imprisonment, backdated to his Dec 9 arrest date.
Anbalagan, 41, admitted to throwing concrete pieces at a bus and in the direction of police vehicles.
He was sentenced to 18 months in prison, backdated to his Dec 8, 2013, arrest date. — The Straits Times / Asia News Network
