As many as 28 South Asian workers, including 24 Indians, were arrested yesterday for alleged rioting in the country on Sunday.
All the accused face charges under "rioting with dangerous weapons", punishable by up to seven years in prison as well as caning.
Meanwhile, Singapore police have released two Bangladeshis after investigations showed they were not involved in the riot.
The other two are an Indian national and a Singapore permanent resident. This means those who are likely to face charges of rioting this afternoon are all Indian nationals, Strait Times reported.
At least 18 people, including 10 policemen, were injured when some 400 people attacked the police and damaged 16 vehicles in an Indian district here, they said.
