Sikander Singh, 27, and Ramandeep Singh, 28, are alleged to have been part of an unlawful assembly with several others near Singapore Post Centre at Paya Lebar on Sunday night.
They are accused of injuring an unknown Bangladeshi, The Straits Times reported today.
Two Bangladeshi nationals, Kamrul Hasan Hazi Abul Basar, 28, and Md Rony Sikder Md Ramzan Sikder, 26, were allegedly part of the illegal assembly when one or more of them caused hurt to an unknown Indian subject.
Preliminary investigations stated there was a dispute between two groups of people before the fight ensued, police said.
Efforts are also ongoing to trace the remaining suspects involved in the fight in the Paya Lebar suburb area.
If convicted, the four face seven years of jail or with fine or canning.
The incident came three months after Singapore's worst riot in four decades when street violence broke out last December involving some 400 migrant workers from South Asia following the death of an Indian national in a bus accident.
Twenty Indian nationals are facing court trial for the December 8 riot which damaged property worth SGD 650,000.
Fifty two Indians and a Bangladeshi have been deported for their role in the rioting. Singapore previously witnessed violence of such scale during race riots in 1969.
