Terror suspect Mohammad Asif was subjected to a three-hour narco analysis test at the Forensic Science Laboratory in Bangalore to extract more information on the terror network in Karnataka, official sources said.
Asif, who had already undergone polygraph and brain mapping tests, was subjected to three-hour narco analysis test, they said.
Asif, a final year MBBS student and a close associate of terror suspects Riyzuddin Naser alias Mohammad Ghouse and Asadulla Abubakker, was arrested by the Corps of Detectives (CoD) on February 9.
Asif's police custody, which was to end on February 18, was extended to March 6 by the First Class Judicial Magistrate (JMFC) Srinivas, after CoD sought extension of his custody to conduct further interrogation.
The application filed by Asif's advocate Jalagar, seeking the court's permission for an interview with his client, will come up before the JMFC on March 28.
Meanwhile, the JMFC court at Hubli remanded Syed Sameer, who was arrested recently by the CoD in connection with his close ties with terror suspect Yaha Kammukutty, to judicial custody till March 6 on Tuesday.
Sameer, according to police, was a nodal member of the banned Students Islamic Movement of India and was a prominent organiser of the group's activities.
