Sin Chew journalist Tan Hoon Cheng was released at 2.30pm today.
Home Minister Datuk Seri Syed Hamid Albar said this at a press conference at the Bukit Aman police headquarters.
"She made the first report so we had to get to the bottom of it and we received information that her life was under threat," he said.
He added that blogger Raja Petra Kamaruddin and Seputeh MP Teresa Kok would continue to be held for investigations and if there was no reason to hold them, that they would be released within the 60 days allowed for by the Internal Security Act.
He explained that RPK had been held after being given sufficient warning but continued to "create tension" while DAP's Kok had touched on sensitive issues, that is the azan call to prayer.
Kok has since denied this allegation that was originally put forward by Umno's former Selangor Menteri Besar Datuk Seri Dr Mohamed Khir Toyo.
Syed Hamid insisted also that the move was not political and it was purely thedecision of the police.
"I can tell you that the police need not refer to me. Under Section 73(1) it is under their discretion but they will let me know.
"I think there has not been any malice on their part. We have acted within the law," he said, adding also that if he interfered in police action, people would say there is a political motive.... selanjutnya.
