Gursharan Singh, 25, who worked as fork lift driver, was charged last week with the murder of another Indian Jasvinder Kaur together with an unknown person at a Balestier Road premises between December 10 and 12.
Kaur's decapitated body was wrapped in a trash bag when it was spotted floating in the waterway between two housing estates.
Besides her still-missing head and hands, 33-year-old Kaur's arms had also been apparently mutilated.
Authorities were currently looking for another Indian national, Harvinder Singh, 33, said to be the dead woman's husband, to assist with police investigations.
