In the period between the Emperor's announcement and the arrival of Allied forces in Malaya sporadic fighting broke out between the Chinese and Malay communities, particularly in Perak. The MPAJA launched reprisals against collaborators in the Malay police force and the civilian population and began to forcibly raise funds. Many in the MPAJA rank and file advocated revolution. A few of the Japanese occupation troops also came under attack from civilians during this period as they withdrew from outlying areas and some defected to the MPAJA.
