"Section 151 (of the Code of Criminal Procedure under which Priyanka Gandhi and others were detained), sub-section 2 says, a person cannot be kept in detention beyond 24 hours. Now it is almost 36 hours. They have not taken Priyanka Gandhi or anyone else to the magistrate," says former Finance Minister and Congress leader P Chidambaram on how the detention of Priyanka Gandhi and other Congress leaders in Uttar Pradesh might be illegal.
