The Chief Judicial Magistrate's court extended the police remand for Singh.
Singh had been arrested on Thursday last in the Aizawl court premises after the District and Sessions Judge Lucy Lalrinthari rejected his bail plea.
All the other accused, including the eight Assam Rifles personnel, and four civilians (two of them employees of Mithipi) were also remanded to judicial custody by the CJM's court.
