Can the police arrest me without telling my parents?

The police have a duty to tell your parents or guardians why you have been arrested. They can ask the police for the charges under which you have been arrested.

If the police have registered an FIR (or first information report), they have a duty to give your parents or guardians a copy of this FIR. An FIR is the document prepared by the police when they get any information about a crime that has occurred.
