Deputy Inspector-General of Police Tan Sri Ismail Omar said in a statement that police were satisfied with the cooperation rendered by Kok during the investigation and there was no longer any reason to continue her detention.
Home Minister Datuk Seri Syed Hamid Albar said the release of the Seputeh Member of Parliament, Teresa Kok, from detention under the Internal Security Act (ISA) was decided entirely by the police without referring to him or requiring his approval.
He said he was in fact informed of the matter after Kok had been released, and believed that the release was made after police investigation revealed that the detention was no longer necessary.
"I don't ask questions because when it comes to police exercising their power, I let them do their work without any hassle.
"And if they feel there is no need to make any recommendations and they are satisfied, they will release in accordance with the powers that they have.
Kok, who is also a Selangor State Executive Councilor, was released at 1.30pm after being detained for eight days under Section 73(1) of the ISA 1960 as she was alleged to have raised racial and religious sentiments.
Syed Hamid said that under Section 73, an individual could be detained for up to 60 days for investigation if the police suspected that he or she was a threat to national security.
He said that his role as the minister was only needed to approve detention that exceeded the 60-day period, where police felt that the extended detention was a necessity.
