Discuss the power of Police to arrest under Cr.P.C

Last it be remembered that the arrest of a person involves an encroachment on his/her personal liberty. Article 21 of the Constitution of India declares that no person shall be deprived of his personal liberty and life except in accordance with procedure established by law. There can be no doubt that the power to arrest any person therefore must be premised on a law which authorizes the same. Police has  a statutory duty to inform the arrestee of the grounds for such arrest as contemplated under Article 22(1) of the Constitution and Section 50 of the Code. If police failed to dischurge its statutory duty the Magistrate must Perform it before remanding the arrested person.
