With the Japanese's bombing Penang, the Regent and his family fled. They were given accommodation in Sidim when the second and more severe bombing of Penang town took place on 11 December 1941, which caused hundreds of civilians to be killed. Upon returning, to Kulim, Tunku found out that all the Police were no longer on duty. Tunku's first concern was to prevent looting and he called all members of the disbanded Kedah Volunteer Force in Kulim to come to his assistance. These men formed a vigilante corps and Tunku arranged for them to patrol the town at night. He was also responsible for the acquiring of emergency food stores from the Government Rice Mill at Bagan Serai in Perak. By 16 December 1941, the Japanese army had occupied the west coast of Kedah, including all the main towns. The Japanese Military Governor of Kedah an assuming office appointed another of Tunku's brothers, Tunku Mohamed Jewa, to be a temporary Regent until the Sultan returned to Alor Setar.
