Power of arrest without a warrant has been entrusted to ___ under the FIA Act.

The correct answer is Sub-Inspector because statutory limitations within the Act restrict warrantless arrests to personnel who hold or exceed this specific operational rank rank.

• Sub-Inspector: This is the correct choice. Section 5(2) of the FIA Act dictates that any member of the agency not below the rank of Sub-Inspector who is authorized by the Director General can execute an arrest without a warrant against individuals suspected of scheduled offenses.
• Incorrect Options:
  • Constable / Assistant Sub-Inspector: These are incorrect. While these lower-ranking officers assist during field actions, they do not possess standalone, independent legal authorization to issue or execute a warrantless arrest under the explicit boundaries of the FIA Act.
  • All of these: This is incorrect because the statutory authority is exclusively bounded to the rank of Sub-Inspector and above.
