In my understanding, it cannot be Section 41 of the Criminal Procedure Code(CrPC). CrPC is a procedural law, its provisions do not define any offence. And it certainly cannot be Section 41; it provides for arrest:
41.When police may arrest without warrant.-
(1) Any police officer may without an order from a Magistrate and without a warrant, arrest any person-
(a) who has been concerned in any cognizable offence, or against whom a reasonable complaint has been made, or credible information has been received, or a reasonable suspicion exists, of his having been so concerned; or
(b) who has in his possession without lawful excuse, the burden of proving which excuse shall lie on such person, any implement of house-breaking; or
(c) who has been proclaimed as an offender either under this Code or by order of the State Government; or
(d) in whose possession anything is found which may reasonably be suspected to be stolen property and who may reasonably be suspected of having committed an offence with reference to such thing; or
(e) who obstructs a police officer while in the execution of his duty, or who has escaped, or attempts to escape, from lawful custody; or
(f) who is reasonably suspected of being a deserter from any of the Armed Forces of the Union; or
(g) who has been concerned in, or against whom a reasonable complaint has been made, or credible information has been received, or a reasonable suspicion exists, of his having been concerned in, any act committed at any place out of India which, if committed in India, would have been punishable as an offence, and for which he is, under any law relating to extradition, or otherwise, liable to be apprehended or detained in custody in India; or
(h) who, being a released convict, commits a breach of any rule made under sub-section (5) of section 356; or
(I) for whose arrest any requisition, whether written or oral, has been received from another police officer, provided that the requisition specifies the person to be arrested and the offence or other cause for which the arrest is to be made and it appears there from that the person might lawfully be arrested without a warrant by the officer who issued the requisition.
(2) Any officer in charge of a police station may, in like manner, arrest or cause to be arrested any person, belonging to one or more of the categories of persons specified in section 109 or section 110.
It cannot be Section 41 of Indian Penal Code (IPC) as this a just a definition clause:
41. "Special law"
A "special law" is a law applicable to a particular subject.
As such, it is important that you ascertain the facts relating to as well nature of the alleged offence against you. If an FIR has been lodged, obtain its copy. All these information could be obtained under Right to Information Act (RTI).
It could be that the police man is just bluffing.
