SFIO arrest powers require recorded belief and Director approval with specified procedural and documentation safeguards. SFIO officers may arrest persons where material gives rise to a recorded reason to believe an offence under section 212; arrests by Additional Director or Assistant Director require the Director's prior written approval and the Director SFIO is the competent authority. Arrests related to Government or foreign companies need prior Central Government approval, with specified notifications. Arresting officers must serve a signed arrest order with a personal search memo, forward sealed copies and materials to the Director SFIO within twenty-four hours, and the SFIO must maintain an arrest register and preserve records for five years. CrPC provisions apply mutatis mutandis.
