A Chief Metropolitan Magistrate court on Tuesday remanded the 2005 Indian Institute of Science (IISc) terror attack suspect Habib Mia in judicial custody for 14 days.

On March 18, the Karnataka Anti Terror Squad (ATS) was given the 37-year-old's four-day transit remand by West Tripura District Magistrate and Collector Milind Ramteke, a day after his arrest in Agartala.

"Habib Mia was in police custody for 10 days. We handed him over for judicial custody after interrogating him. He confessed to helping Sabahuddin, the main accused in the IISc attack here," Additional Commissioner of Police (Crime) S. Ravi told reporters.

The IISc was attacked on December 28, 2005, while a convention was underway. A scientist was killed and five persons injured as attackers lobbed hand grenades and opened fire at the gathering.

"Mia told police of his meeting with Sabahuddin at a mosque in Agartala for three days. Mia said he received Rs 800 from Sabahuddin for helping him cross into Bangladesh," said Ravi.
