The cupboard in which flex banners related to the Vijayan's rally were kept, part of a wall and floor were damaged in the fire late last night, when unidentified persons broke open the door and entered the office at Thokkottu Junction, police said.
The vandalism came to light this morning when newspaper delivery man noticed it and informed the persons concerned, they said.
Police, who visited the spot, said investigation was underway.
The BJP District unit has also announced to support a bandh called by Vishwa Hindu Parishad (VHP), Hindu Jagrane Vedike and several other organisations on February 25 opposing Vijayan's visit.
BJP has alleged the CPI(M) heading the ruling LDF in Kerala was behind the killing of members of parties that held different political views and Vijayan was responsible for the current "volatile political situation" in the state.
