Justice Minister Somsak Thepsuthin signed the transfer order on Wednesday (Jan 18), reports the Bangkok Post.
Effective immediately, Mr Traiyarit was moved to the Central Institute of Forensic Science (CIFS), to serve as acting director.
CIFS director Pol Maj Gen Suriya Singhakamol takes over as acting director at the DSI.
A source said the sudden transfer of the DSI chief was linked to allegations that Mr Traiyarit’s right-hand man had sought cooperation from a senior officer at the Patrol and Special Operations Division, better known as 191 Police, to coordinate with a deputy commissioner at the Metropolitan Police Bureau and obtain court approval for the search at the former home of the Nauru consul-general in Bangkok on Dec 22 last year.
Police and DSI officials involved in the search allegedly extorted about B9.5 million in bribes in exchange for the release of 11 Chinese nationals found hiding on the premises.
On Monday, Pol Gen Surachate Hakparn, deputy national police chief, said five DSI officials, nine policemen, including from the Patrol and Special Operation Division, a military police officer and a Chinese-born interpreter were involved in the alleged extortion and bribe payment.
The house was formerly rented by a consul-general of the Republic of Nauru.
Former politician and massage parlour tycoon Chuvit Kamolvisit posted on his Facebook page on Sunday, alleging that the consul-general’s former house was now sheltering illegal Chinese nationals and served as a place to forge passports and visas.
Mr Chuvit on Tuesday posted a document about an investigation by the Office of the Consulate General of the Republic of Nauru. It found that a stamp shown on a lease agreement dated on Sept 2, 2022 was similar to that used by the consul-general of the Republic of Nauru in Thailand.
However, it had no document or details regarding the use of the official stamp for the lease agreement. The consulate office insisted it had not signed the lease agreement, according to the document posted by Mr Chuvit.
The residence was rented by Chinese nationals running “grey businesses”, according to Mr Chuvit. He alleged that those Chinese used false diplomatic licence plates on their van and falsified the signature of the former consul-general to rent the luxury house.
During the search on Dec 22, the officers arrested 11 Chinese nationals, one of them on Interpol’s Red Notice list, and found B8mn in cash. The Chinese had allegedly escaped a raid at the illegal Jinling pub complex, which catered to Chinese tourists, on Charoen Rat Rd in Bangkok on Oct 26.
All the suspects found in the house were released in exchange for B5.5mn of the seized funds. Whistleblower Chuvit also alleged that the officers had demanded an additional B4mn, to be picked up from a petrol station by the Chinese interpreter.
On Tuesday, the DSI chief insisted the DSI had not ordered the accused officials to search the former consul-general’s premises on Dec 22. He also denied reports that his right-hand man coordinated with 191 Police in organising the raid.
