People are sending messages through social media accusing Thaksin Shinawatra of being behind these events," said Noppadon, who once served as foreign minister in a Thaksin proxy government.
"This is slander and defamation. All the former prime ministers love and worry for the country. None of them would condone such evil acts," he said.
In order to protect his reputation, Thaksin has assigned his lawyers to file a police complaint this week against those making accusations against him, Noppadon said.
