Abubacker and Abdur Rahman belonging to the 'Base Movement' were arrested from Madurai last night, they said.
They were detained based on interrogation of five other members of the little-known movement detained by the National Investigation Agency in November last year in Madurai in connection with low-intensity blasts in court complexes including in Mallapuram and Kollam in Kerala and Chitoor in Andhra Pradesh.
A low-intensity Improvised Explosive Device had gone off in a car parked in Malappuram Judicial Magistrate Court complex on November 1 last year. No one was injured in the incident.
