The Congress in Kerala today demanded a public apology from Chief Minister Pinarayi Vijayan in the backdrop of actor Dileep's arrest in the abduction and assault case of a Malayalam actress last year.

In a statement here, Leader of Opposition in the Kerala Assembly Ramesh Chennithala said Vijayan had stated during the initial stage of the probe that there was no conspiracy angle in the case and it was a "figment of imagination" of the prime accused, 'Pulsar' Suni. 

The Congress leader alleged that this statement of the chief minister had "affected" the investigation. Kerala Congress chief M M Hassan said the chief minister, who also holds the home portfolio, should relinquish it.

Vijayan had, from the beginning, insisted that there was no conspiracy in the case, he said in a statement. "It was the creation of the prime suspect. It (the crime) was hatched in his mind," Pinarayi Vijayan stated in a public function on 24 February. But the CM's statement surprised many as the police were yet to complete the interrogation of the suspects arrested when he dismissed it as a handiwork of the prime accused. 

Later the CM 'clarified' that his statement was distorted by the media. "I was not quoting any official information. What I said was that the media need not go after the conspiracy. Let the police investigate it," he said. 

On February 17, the popular actress, who has also worked in Tamil and Telugu films, was abducted and allegedly molested inside her car for two hours at a busy area in Kochi by the accused, who had forced their way into the vehicle. 

Popular Malayalam actor Dileep was arrested in connection with the case on Monday.
