DSI director general Tharith Pengdith said the Democrat Party had no cause to suspect the warrant cancellation.
“The DSI has never initiated or recommend for the lifting of the warrant,” he said.
The warrant for the Thaksin’s arrest in question is related to terrorism charges in connection with the last year’s political disturbances.
Tharith said the DSI had completed its investigative report recommending indictment and prosecution on the Thaksin case. The report is being reviewed by the prosecutors.
He also said the DSI computer system did not malfunction prompting a erronous delete of Thaksin’s warrant as speculated.
