The man was found collapsed near Connaught Place at about 9pm on 7 November with severe head injuries. He was taken by ambulance to Queen Mary Hospital and died on 10 November after about three days in hospital.
Police said their preliminary investigation indicated that he had argued with two fellow Filipino men, reportedly over his attitude, before they allegedly punched and kicked him.
