Several Thai police websites were temporarily brought down by hackers on Tuesday in an apparent response to the death sentences given to two Myanmar citizens for the murder of two British tourists, officials said.
Myanmar migrant workers Zaw Lin and Wai Phyo were found guilty in late December of the rape and murder of Hannah Witheridge and the murder of David Miller on the resort island of Koh Tao in September 2014.
The death sentences handed out by a Thai court prompted a series of protests in neighbouring Myanmar, with protesters saying that the workers were scapegoats, and that the trial was flawed.
"Apparently these attacks are in response to the recent (Koh Tao murder) case," said Police General Suppaset Chokchai. "We are currently verifying whether these claims are true and how best to proceed."
Searches for the Thai Metropolitan Police website on Google returned with the result: “Blink Hacker Group, Failed Law We want Justice!"
This and other related sites appeared to be back in operation by 4:40 pm (1140 GMT).
On Monday, the Thai embassy in Yangon said that consular services would remain closed until Friday "due to the ongoing demonstration which have caused difficulties in access to the compound."
Myanmar's ambassador to Thailand, U Win Muang, has told reporters that the embassy was monitoring the appeals process closely and hoped that the workers would be treated fairly.
