The Department of Special Investigation (DSI) yesterday summoned three opposition MPs to report themselves for detention in connection with the recent political turmoil and riots.
Tharit said the DSI would request court permission for detention of the three politicians. "This is the normal practice for anyone accused in similar cases," he added.
If any of the politicians fails to show up, the DSI will have sufficient cause to seek court permission to issue an arrest warrant, Tharit said.
"But the DSI has no intention of hunting down or speeding up detention. This is part of the normal procedure," he said.
The three politicians are accused of involvement in acts of "terrorism" for playing a leading role in the recent anti-government rally by the red shirts.
Regarding an international arrest warrant for fugitive ex-premier Thaksin Shinawatra - whom the DSI accuses of "terrorism" for his connection with the red-shirts' riots -Tharit said yesterday the warrant had been sent to the International Criminal Police Organisation, generally known as Interpol.
The DSI chief said he had notified the Royal Thai Police, the Office of Attorney-General and the Ministry of Foreign Affairs to send the arrest warrants abroad.
