  14. Offences to be cognizable 
  Notwithstanding anything contained in 42[the Code of
  
  Criminal Procedure, 1973 (2 of 1974)], any offence punishable under this Act
  
  shall be deemed to be a cognizable offence within the meaning of that Code:
  Provided  that, notwithstanding anything contained in
  
  that Code,- 
  ( i ) arrest without warrant may be made
  
  only by the special police officer or under his direction or guidance, or
  
  subject to his prior approval;
  (ii) when the special police officer requires any officer
  
  subordinate to him to arrest without warrant otherwise than in his presence any
  
  person for an offence under this Act, he shall give that subordinate officer an
  
  order in writing, specifying the person to be arrested and the offence for
  
  which the arrest is being made; And the latter officer before arresting the
  
  person shall inform him of the substance of the order and, on being required by
  
  such person, show him the order;
  (iii) any police officer not below the rank of 42[sub-inspector]
  
  specially authorized by the special police officer may, if he has reason to
  
  believe that on account of delay involved in obtaining the order of the special
  
  police officer, any valuable evidence relating to any offence under this Act is
  
  likely to be destroyed or concealed, or the person who has committed or is
  
  suspected to have committed the offence is likely to escape, or if the name and
  
  address of such a person is unknown or there is reason to suspect that a false
  
  name or address has been given, arrest the person concerned without such order,
  
  but in such a case he shall report, as soon as may be, to the special police
  
  officer the arrest and the circumstances in which the arrest was made.
