IPC Section 507 and BNS Section 351(4): Criminal Intimidation by Anonymous Communication

Meaning of criminal intimidation by anonymous communication

Criminal intimidation generally involves threatening another person with injury to their person, reputation or property, or to the person or reputation of someone in whom they are interested, with the legally required intention to cause alarm or compel action or omission. Anonymous criminal intimidation adds the feature that the offender communicates without revealing identity or deliberately conceals the name or place of residence from which the threat originates.

Original text of IPC Section 507

Whoever commits the offence of criminal intimidation by an anonymous communication, or having taken precaution to conceal the name or abode of the person from whom the threat comes, shall be punished with imprisonment of either description for a term which may extend to two years, in addition to the punishment provided for the offence by the last preceding section.

Current law: BNS Section 351(4) substantially carries forward this additional punishment. The substantive definition of criminal intimidation is in BNS Section 351(1), while Sections 351(2) and 351(3) provide the ordinary and aggravated punishments.

Essential ingredients of IPC 507 and BNS 351(4)

1. Threat amounting to criminal intimidation: The communication must satisfy the definition in IPC Section 503 or, for current offences, BNS Section 351(1).
2. Required intention: The threat must be intended to cause alarm, or to induce a person to do something they are not legally bound to do or omit something they are legally entitled to do as a means of avoiding the threat.
3. Anonymous communication or concealment: The offender uses an anonymous communication or takes precautions to conceal the name or abode of the source.
4. Proof connecting the accused: The evidence must connect the alleged offender to the communication and establish the statutory elements.

The context, actual words, recipient, manner of transmission and surrounding circumstances matter. An unpleasant remark or ordinary dispute is not enough by itself.

Punishment under IPC 507 and BNS 351(4)

Additional imprisonment up to two years may be imposed for anonymous or concealed-source criminal intimidation. This is in addition to the punishment for the underlying intimidation offence, not a replacement for it.

• Ordinary criminal intimidation: Under BNS Section 351(2), imprisonment up to two years, or fine, or both.
• Aggravated criminal intimidation: Under BNS Section 351(3), imprisonment up to seven years, or fine, or both, where the threat falls within the aggravated statutory categories, including death or grievous hurt.
• Anonymous or concealed-source threat: BNS Section 351(4) provides a further imprisonment term up to two years, in addition to the punishment under the relevant preceding provision.

For offences alleged to have occurred before 1 July 2024, IPC Sections 503, 506 and 507 may remain relevant under applicable savings provisions. The date and facts of the alleged offence should be checked.

Police complaint, classification and electronic evidence

A person receiving a threatening anonymous letter, phone call, email or online message can preserve the original communication and approach the police with the relevant details. The police or competent Magistrate will assess the alleged offences and the procedure under the Bharatiya Nagarik Suraksha Sanhita, 2023 (BNSS).

Bail, cognizability and investigation must be assessed under the applicable First Schedule of the BNSS, the exact subsection invoked and any other offences alleged. Do not assume that every threat is classified identically, particularly where aggravated threats or additional statutory offences are alleged.

Evidence to preserve

• Original letters, envelopes, call records, emails, messages and screenshots, with dates and times.
• Phone numbers, email headers, usernames, profile links and other identifying information where available.
• Any witness details and contemporaneous records of the incident.
• Electronic records in a form that can be authenticated under the Bharatiya Sakshya Adhiniyam, 2023, including the applicable certificate requirements where necessary.

Practical illustrations

Anonymous message threatening serious injury

A person sends an unsigned message threatening to seriously injure a recipient with the intention of causing alarm. If the sender is identified and the elements are proved, aggravated intimidation and the additional anonymous-communication provision may be considered.

Concealing the source of a threatening call

A caller deliberately hides their identity while threatening unlawful injury to compel another person to withdraw a lawful complaint. The anonymity and the coercive purpose are relevant to the legal assessment.

Anonymous criticism without a threat

An unsigned message expressing criticism or disagreement without a threat or the required intention does not become criminal intimidation merely because the author is unknown.
