Four more Indian nationals were charged in court on Thursday afternoon for their involvement with Sunday's riot in Little India.

Sellamuthu Elangovan, 45, Ammasi Venkatesan, 27, Selarasu Dhanapal, 25, are accused of throwing pieces of hardened concrete at the police officers responding to the melee along Race Course Road.

The fourth man, Arumugam Karthik, is said to have been a member of an unlawful assembly and attacking - with a dustbin, wooden stick, hardened concrete, bottles and a metal drain cover - the private bus, which was previously reported to have run over and killed Indian national Sakthivel Kumaravelu at the junction of Tekka Lane and Race Course Road. The 24-year-old is also accused of overturning and later setting on fire a police vehicle during the chaos.

This now brings the total number of accused persons facing charges for Sunday's incident in Little India to 31.

This after the first group of 27 were hauled up to court over Tuesday and Wednesday.

They have been remanded for further investigations and will return to court on Dec 19.
