Delhi Police detained Abhijeet Dipke and others from inside a plane: Can they do so? What does the law say?

Delhi Police detained Cockroach Janata Party founder Abhijeet Dipke and aides Saurav Das and Ashutosh Ranka after their aircraft landed in the capital. The action came before a protest demanding Chief Election Commissioner Gyanesh Kumar’s resignation. Critics accused the election authorities of removing about 13 crore voters from a draft roll.

Police reportedly invoked Sections 126 and 170 of the Bharatiya Nagarik Suraksha Sanhita, 2023. Section 126 concerns security for keeping peace. Section 170 concerns arrest to prevent a cognisable offence. The police boarded the aircraft and took action before the proposed rally, rather than responding to an incident during flight.

Dipke and the others were later released from preventive arrest. The episode raised a broader legal question: whether police may enter an aircraft and arrest someone there. Experts said they can act lawfully, but must show proper grounds, follow procedure, justify any force, and respect constitutional safeguards.

Police can arrest or detain someone inside an aircraft, because the aircraft is not immune from lawful police action. The same general arrest rules apply under the Bharatiya Nagarik Suraksha Sanhita, 2023, whether the arrest occurs at an airport or elsewhere. The location does not remove personal rights or police duties.

Police may execute a warrant or arrest without one under Section 35 when its conditions are met. They must also satisfy legal requirements for entering the aircraft and obtain permissions from the authorities concerned. Under Section 43, force is permitted only when someone resists or tries to evade arrest, and only to the extent necessary. Officers must explain the grounds and need for their action.

A protest plan alone does not automatically justify detention. Section 170 requires knowledge of a design to commit a cognisable offence that cannot otherwise be prevented. Articles 21 and 22, along with D K Basu safeguards, limit arbitrary arrest and detention.

Preventive arrest is an action taken to stop a feared offence or disturbance before it occurs. It is different from arrest after an offence has already been committed. Because it restricts liberty without a completed offence, police must meet the specific legal conditions and cannot rely only on suspicion or a person’s political activity.

Section 126 of the BNSS concerns security for keeping peace. An Executive Magistrate may begin proceedings against someone likely to breach the peace or disturb public tranquillity, asking why that person should not execute a bond to maintain peace. Section 170 permits arrest when police know of a design to commit a cognisable offence and believe it cannot otherwise be prevented.

In Dipke’s case, police reportedly invoked both provisions before the rally. Experts stressed that merely travelling to a protest does not itself satisfy Section 170. The legality therefore depends on the facts, evidence, necessity, and procedure followed.

Section 170 of the Bharatiya Nagarik Suraksha Sanhita permits preventive arrest when a police officer knows of a design to commit a cognisable offence and believes the offence cannot otherwise be prevented. It is an exceptional power because it acts before the suspected offence occurs. The power must still be used on lawful grounds and according to procedure.

Under Section 170, a person arrested preventively cannot generally be detained for more than 24 hours from arrest unless continued detention is authorised under another legal provision. The period needed for travelling from the arrest location to the Magistrate is excluded from that calculation. Further custody therefore requires legal authorisation, rather than simply a police decision.

The supplied article explains the purpose of Section 170 but does not give this time limit. It does stress that travelling to a protest, by itself, is insufficient. Articles 21 and 22 and the D K Basu safeguards remain relevant throughout arrest and custody.

The key difference is purpose. Crew or authorities may restrain an unruly passenger to address an immediate threat to aircraft safety or security. That action is connected directly to protecting people on board, the aircraft, and the flight. Aviation laws cover conduct such as violence, intimidation, disobedience of lawful pilot instructions, and acts endangering flight safety.

Detaining someone because they are travelling to a planned protest is different. It is an independent law-enforcement action, not automatically an aviation-safety response. Police must rely on general arrest law, such as the conditions in Section 35 or the preventive requirements in Section 170. Any force must be necessary and proportionate under Section 43.

The article says the mere possibility of a protest does not itself justify detention. Police must explain why entering the aircraft was necessary, identify the lawful grounds, and follow arrest safeguards. The facts surrounding each detention therefore matter more than the aircraft’s location alone.

Arrest does not end a person’s legal protections. The Supreme Court’s guidelines in D K Basu v State of West Bengal require police to follow safeguards during arrest and custody. These measures help create a record, inform the person of what is happening, and reduce the risk of secret or arbitrary detention.

Police must prepare an arrest memo and inform the arrested person of the grounds of arrest. They must notify a relative or friend and ensure medical examination when required by law. The article also says police must justify force and explain why entering the aircraft was necessary. Section 43 permits force only when a person resists or tries to evade arrest, and only as much as necessary.

These duties apply whether the arrest occurs inside an aircraft, at an airport, or elsewhere. Assistance from the Central Industrial Security Force cannot make an otherwise unlawful arrest lawful. Compliance with the BNSS and constitutional safeguards remains essential.

Articles 21 and 22 protect people because arrest and detention directly restrict personal liberty. Article 21 safeguards life and personal liberty, while Article 22 provides constitutional protections for people who are arrested or detained. Together, they require state action to remain lawful and protect individuals from arbitrary deprivation of freedom.

These protections matter in situations such as the Dipke detention, where police acted before a proposed protest. Preventive powers can be lawful, but they must meet defined conditions. Section 170 requires knowledge of a design to commit a cognisable offence that cannot otherwise be prevented. Section 126 involves proceedings to secure peace, not automatic punishment for political activity.

The safeguards also require practical accountability. The D K Basu guidelines include an arrest memo, information about the grounds, notification of a relative or friend, and medical examination when required. These rules apply inside an aircraft as well as elsewhere, and help courts assess whether detention was lawful.
