Introduction

BNS Section 351(4) of the Bharatiya Nyaya Sanhita, 2023 deals with criminal intimidation committed through anonymous communications or by concealing the identity of the person making the threat. The law treats anonymous threats more seriously because the victim may be unable to identify the source of the intimidation.

The provision supplements the offence of criminal intimidation under BNS Section 351(1). Where a person not only threatens another but also hides their identity or sends the threat anonymously, an additional punishment may be imposed.

BNS Section 351(4) replaces IPC Section 507 and continues the legal framework relating to anonymous threats and intimidation.

What is BNS Section 351(4)?

BNS Section 351(4) applies when a person:

  • Commits the offence of criminal intimidation; and
  • Does so through an anonymous communication; or
  • Takes precautions to conceal their name or place of residence from the person receiving the threat.

The provision imposes additional punishment because the offender deliberately hides their identity while making the threat.

Bare Act Text

“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 under sub-section (1).”

In Simple Words

If a person threatens another person and deliberately hides their identity, uses an anonymous message, fake account, anonymous letter, or conceals where the threat comes from, they may be punished under BNS Section 351(4) in addition to the punishment for criminal intimidation.

Essential Ingredients of BNS Section 351(4)

To establish an offence under BNS Section 351(4), the prosecution generally needs to prove:

  1. Criminal intimidation was committed.
  2. The threat was communicated anonymously; or
  3. The accused took precautions to conceal their identity or residence.
  4. The communication was intended to hide the source of the threat.
  5. The accused was responsible for making or sending the threat.

The offence under this section cannot generally exist without the underlying offence of criminal intimidation.

Meaning of Anonymous Communication

An anonymous communication is a communication in which the identity of the sender is hidden or not disclosed.

Examples may include:

  • Anonymous letters.
  • Unsigned threatening notices.
  • Threatening emails sent without revealing identity.
  • Threats sent through fake social media accounts.
  • Messages sent through concealed or untraceable means.

The exact circumstances of each case determine whether the communication is truly anonymous.

Concealing Name or Abode

The section also applies when the offender takes deliberate steps to hide:

  • Their name.
  • Their address.
  • Their residence.
  • Their identity as the sender of the threat.

Even if the communication is not completely anonymous, liability may arise if precautions are taken to conceal the source of the threat.

Relationship with Criminal Intimidation

BNS Section 351(4) is not an independent offence by itself. It operates along with the offence of criminal intimidation under BNS Section 351(1).

The prosecution must first establish criminal intimidation. Once that is proved, the additional element of anonymity or concealment may attract further punishment under sub-section (4).

Anonymous Threats Through Electronic Communication

The provision can apply to modern forms of communication where threats are transmitted anonymously through:

  • Emails.
  • Messaging applications.
  • Social media platforms.
  • Online forums.
  • Electronic communication systems.

The crucial factor is whether the sender intentionally concealed their identity while making the threat.

Punishment Under BNS Section 351(4)

A person convicted under BNS Section 351(4) may be punished with:

  • Imprisonment up to 2 years.

This punishment is in addition to the punishment provided for criminal intimidation under BNS Section 351(1).

Therefore, an offender may face punishment for both criminal intimidation and the additional offence of anonymity or concealment.

Classification of the Offence

Criteria Status
Cognizable Non-cognizable
Bailable Bailable
Compoundable Non-compoundable
Triable By Magistrate First Class

BNS Section 351(4) is a non-cognizable and bailable offence. It is non-compoundable and triable by a Magistrate First Class.

Bail Under BNS Section 351(4)

Since the offence is bailable, an accused person may seek bail in accordance with the applicable legal procedure.

The grant of bail is generally available subject to compliance with legal requirements.

Which Court Has Jurisdiction?

According to the classification provided, offences under BNS Section 351(4) are triable by a Magistrate First Class.

The Magistrate having territorial jurisdiction over the place where the threat was communicated or received ordinarily conducts the trial.

Step-by-Step Legal Process

  1. A complaint regarding the anonymous threat is made.
  2. Police examine the communication and surrounding circumstances.
  3. Evidence relating to the threat is collected.
  4. The source of the communication may be investigated.
  5. Witness statements are recorded.
  6. Charge sheet may be filed before the competent court.
  7. Charges are framed.
  8. Trial is conducted.
  9. Evidence is examined.
  10. Judgment is delivered.

Old Law vs New Law (IPC to BNS Mapping)

Aspect IPC Section 507 BNS Section 351(4)
Law Indian Penal Code, 1860 Bharatiya Nyaya Sanhita, 2023
Offence Criminal Intimidation by Anonymous Communication Criminal Intimidation by Anonymous Communication
Anonymous Threats Covered Covered
Concealment of Identity Covered Covered
Additional Punishment Up to 2 Years Up to 2 Years

BNS Section 351(4) substantially continues the provisions previously contained in IPC Section 507.

Defences Available to the Accused

Depending upon the facts of the case, possible defences may include:

  • No criminal intimidation occurred.
  • The communication did not contain any threat.
  • The accused was not the sender of the communication.
  • Identity was not intentionally concealed.
  • False implication.
  • Lack of sufficient evidence.
  • Absence of the essential ingredients of criminal intimidation.

Real-Life Illustration

Suppose a person sends an unsigned letter threatening harm unless money is paid. The sender deliberately conceals their identity and address. If the communication amounts to criminal intimidation, the sender may also be prosecuted under BNS Section 351(4).

Similarly, if an individual uses a fake online account to send threatening messages while hiding their identity, liability under this provision may arise in addition to the punishment for criminal intimidation.

Conclusion

BNS Section 351(4) provides enhanced punishment for criminal intimidation committed through anonymous communications or by concealing the identity of the person making the threat. The provision recognises that anonymous threats create greater fear and make it more difficult for victims to identify the offender.

The offence is non-cognizable, bailable, non-compoundable, and triable by a Magistrate First Class. By imposing additional punishment, the law seeks to discourage anonymous intimidation and protect individuals from concealed threats.
