The Crime Suppression Division (CSD) has found new evidence in connection with the 30-million-baht lottery scandal involving disputed winning tickets but it declined to say which claimant this favours: a local teacher or a police officer.
CSD commander Maitree Chimcherd insisted Thursday the fresh evidence will be useful as it can confirm or discredit the truth of statements given by two witnesses in the 30-million-baht dispute.
They were introduced by Preecha Kraikruan, the teacher in Kanchanaburi who claims he purchased the jackpot-winning tickets.
The findings were compiled by an investigative team from the CSD's sub-division 5 that was sent to the western province to investigate the case.
The team was led by CSD deputy chief Chakrit Sawasdee.
Mr Preecha lodged a police complaint in December against Pol Lt Jaroon Wimol, who was in possession of the winning tickets at the time, for embezzlement. As a result, the cash prizes were frozen pending conclusion of the probe.
The case was originally handled by Provincial Police Region 7, which oversees Kanchanaburi and other western provinces.
It concluded Mr Preecha was the real owner of the tickets based on the testimony of witnesses.
On Monday Pol Gen Chakthip Chaijinda, the national police chief, ordered regional police to transfer the case to the CSD after the probe results were met with scepticism from the public.
A police source said the regional investigators overlooked key evidence when wrapping up the probe.
The case took another turn the following day as Pol Lt Jaroon submitted an audiotape recording of phone calls between Mr Preecha and Ratanaporn Supathip, a female lottery vendor who allegedly sold him the tickets.
The segment of the clip most relevant to the investigation involves Mr Preecha denying to the vendor that he had won.
Asked whether more than 40 witnesses questioned by the regional police would be summoned to give testimony, Pol Maj Gen Maitree said the CSD was not in a position to do this yet as no official order has been issued.
Once it receives such an order the investigation report will be forwarded to the proper division, which will consider who to summon, he said.
Pol Maj Gen Maitree also denied a rumour that Ms Ratanaporn was detained and subjected to an "intense interrogation".
He said he had no knowledge of this but that all of the CSD's investigative procedures could be examined as they were carried out transparently.
Also Thursday, Sittra Biabangkeod, secretary-general of the Lawyers for People Foundation, posted a message on his Facebook account urging the CSD to launch a probe into nine issues relating to the lottery case.
The issues include: who sold the lottery tickets; how many tickets were purchased, and how much did they cost in total; was the person who reportedly found the tickets on the ground male or female.
Pol Col Chakrit said all of the issues requested by Mr Sittra have already been included in the comprehensive police investigation.
