The PFI in Kerala called for a statewide hartal on September 23.
Masked men and miscreants went on the rampage in different parts of Kerala during the dawn-to-dusk hartal, damaging State-run buses and ambulances, injuring policemen and commoners, and vandalising shops and threatening the public.
On Sunday, the raids were on establishments owned by the PFI workers here, and various electronic devices, including mobile phones and laptops, were seized, the police said.
