The suspected hacker of the Prime Minister's Office website, a Nakhon Sri Thammarat man, met police investigators on Friday and denied posting the offensive message that humiliated the prime minister.
The PM's Office website was hacked around noon on Wednesday with a message posted alongside a doctored image of a laughing Prime Minister Yingluck Shinawatra. The message was derogatory, insulting the premier's intelligence and sexual morality.
Narongrit Suksarn, aka Window 98se, who matches the description of the suspected hacker given by Deputy Prime Minister Chalerm Yubamrung on Thursday, insisted that he did not post the inappropriate message on the PM's Office website.
He met Pol Gen Pisit Paoin, commander of the Technology Crime Suppression Division. Mr Narongrit said he suspected that he had been set up by the "Unlimited Hack Team", of which he used to be a member, but no is longer associated with.
Mr Narongrit said that he decided to meet police to declare his innocence and was ready to provide information on how websites can guard against being hacked.
Pol Maj Gen Pisit said the police will question Mr Narongrit and examine the computer he uses. If he is innocent, he may be able to help the police track down the real hackers.
However, he admitted it would be difficult to find the digital evidence needed to prove who committed the offence.
The hackers were skillful and may be able to cover their tracks and mislead the investigation. Police have around 20 suspects in total, he said.
