Jayendra Saraswati was arrested on November 11 and remanded in judicial custody for the murder of Varadaraja Perumal temple Manager Sankararaman on September 3.

Replying to a question, the DSP said a decision on whether to summon the junior seer of the mutt, Vijayendra Saraswati, for questioning will be taken after the interrogation of his brother Raghu.

Raghu was grilled for nearly four hours on Friday. Premkumar said the questioning will continue.

The DSP said Appu, who allegedly organised the murder, and contractor Ravi Subramaniam, who is accused of disbursing money to the assailants, are suspected to be hiding outside Tamil Nadu.
