In indian cyber laws when police wants to trace a mobile number... they have to get warrant ? Is a warrant needed to approach a network operator like JIO ? Or the SP or DC can sign the request ? Some say even the inspector SHO can get the mobile subscribers info and CDR records. How do they do it ? And also as per law.... the operator will give info only for the number requested or can the police ask the operator if the subscriber has other numbers also in his name and will the operator reveal this. Or is it like police can only get info for specific numbers which they mention and have got warrant/permission for ?
