There are several criminal authorities handling IP cases. The police are undertaking IP cases on an ad hoc basis only - and probably not now martial law is in effect. The DSI's IP teams have also had to move their office from the government complex on Chaeng Wattana Road to Thailand Post Office's headquarters on the same road. A number of files are in fact trapped in the old office and cannot be actioned. The Prosecutors at the IP court likewise had to relocate to the Criminal Court on Ratchadapisek Road, but have recently moved back to their permanent office.
