  • Permits the police officer to take the person into custody.

If must be kept in the mind that there are varieties of the warrants.

Cognizable and Non-Cognizable offenses

Any act which is punishable under the law is the offense. Actus Reus and mens rea or the necessary elements of a crime. Any act without guilty intention is not liable under criminal law. The intention and motive are both different elements.

The offenses can be divided into two types:

  • Cognizable
  • Non Cognizable

Cognizable offense

The offense where the police are authorized to take the direct cognizance of the crime at its own is known as the cognizable offense. The police have the power to arrest the person without warrant. In the case of cognizable offense, the accused arrested by the police will be produced before the magistrate, in 24 hours from the arrest. These crimes are normally non-bailable. The FIR (first information report) can be file only in the cognizable cases. These offenses are severe such as; rape, murder, rioting, dowry death, etc.


The offense where the police are not authorized to take the cognizance of the crime at its own is known as Non-Cognizable offense. The police must have the warrant issued by the court to arrest the person. The police neither can arrest the person who did the Non-Cognizable offense nor can start the investigation in that case without the warrant. These crimes are listed in the first schedule of the IPC and are bailable. The FIR is not lodged in the non-cognizable offense. The person can only lodge the criminal complaint. After that, the magistrate will order the police to start the investigation.

Examples, cheating, forgery, assault, etc.

Difference between Cognizable and Non-Cognizable offenses

S.NO. Cognizable Non-Cognizable
1 Police can take cognizance without a warrant. Police cannot take cognizance without a warrant.
2 There is no need to take prior approval from the court. There must be prior approval of the court to start the investigation.
3 It covers the heinous crimes. It covers comparatively less heinous crimes.
4 FIR is lodged in the crime. A criminal complaint is lodged in the crime.
5 The punishment is more than three years. The punishment is less than three years.
6 The offenses are non-bailable. The offenses are bailable.
7 Murder, Rape, Rioting, etc. Assault, Forgery, Defamation, etc.



I conclude my article with my word that the [police officer] cannot arrest the person in the case where the person has committed the non-cognizable offense or against whom the complaint has been made or the credible information is not received except with the warrant of the court.
