Section 17

A police officer may without warrant arrest any person suspected of the commission of an offence under this Act or of the commission in a proclaimed area of any of the offences referred to in section 27.

A police officer may in a proclaimed area without warrant arrest any person in respect of whom he has reason to believe that he is a person to whom section 13(1) applies and any person so arrested may be detained for a period not exceeding 24 hours, pending a decision as to whether an order under that section should be made.

A police officer may in a proclaimed area arrest any person ordered to be excluded from that area under section 13 and may detain the person for a period not exceeding 24 hours for the purpose of removing him from the area.

Any person detained under the powers conferred by this Act shall be deemed to be in lawful custody and may be detained in any prison or in any police station or in any other similar place authorised generally or specially by the Commissioner of Police.

Every offence against this Act or punishable under section 27 and every offence committed in a proclaimed area against the provisions of any written law for the time being specified in the Second Schedule, shall be seizable and non-bailable for the purposes of the Criminal Procedure Code [Cap. 68].
