Panusak filed the Bt50-million lawsuit in the Central Criminal Court for Corruption and Misconduct Cases in Bangkok.

The raids were part of an ongoing DSI investigation into the evasion of taxes on car imports and the theft of vehicles in Britain. Panusak has not been charged with any crime.

Panusak had on Monday vowed to sue the DSI because the “unlawful” raids and confiscations from his two showrooms had dealt his company a heavy financial blow.

He insisted that all of the luxury cars impounded by the DSI had been imported in accordance with proper procedures.
