After he was arrested, the police took him to police district headquarters for interrogation.

Police officials said that during  initial interrogation the arrested youth said he was a resident of a village nearby Purnea and pleaded his innocence. The police however will interrogate him to know his intentions and how and why he entered the barricade.
