Hello Questioner!
In the year 2013. by a law called Criminal Law (Amendment) Act of 2013, Stalking is made as a crime under Indian penal code, and it is defined in Section 354-D of Indian Penal Code as follows:
Stalking
"(1) Any man who—
follows a woman and contacts, or attempts to contact such woman to foster personal interaction repeatedly despite a clear indication of disinterest by such woman; or
monitors the use by a woman of the internet, email or any other form of electronic communication,commits the offence of stalking;
Provided that such conduct shall not amount to stalking if the man who pursued it proves that—
it was pursued for the purpose of preventing or detecting crime and the man accused of stalking had been entrusted with the responsibility of prevention and detection of crime by the State; or
it was pursued under any law or to comply with any condition or requirement imposed by any person under any law; or
in the particular circumstances such conduct was reasonable and justified.
(2) Whoever commits the offence of stalking shall be punished on first conviction with imprisonment of either description for a term which may extend to three years, and shall also be liable to fine; and be punished on a second or subsequent conviction, with imprisonment of either description for a term which may extend to five years, and shall also be liable to fine. "
It is the police, who has powers under Code of Criminal Procedure, to take cognizance of the offence of stalking (as defined under section 354-D of IPC), and to initiate investigation, and to investigate and file charge-sheet against you for trial of that offence.
But under Criminal Procedure Code, the offence, though Cognizable, yet it is a BAILABLE offence. This means that the police have the power to grant bail to you, in case any FIR is registered against you. In case of bailable offence, it is rather your right to get bail. Assuming that she goes to police to lodge an FIR, and police approach you, offer them bail, and you should be saved from arrest. So no need to fear about arrest.
You said that the complaint which she would file is false. So as regards the falsity of her report, that should become clear to police during investigation, as a consequence of which police souldn't file charge-sheet in the court.
But if this doesn't happen and still police file charge-sheet against you in the court, then you will have to face the trial, and during trial, destroy the prosecution case and to establish your innocence.
In case of your acquittal, afterwards, you may file a civil suit for damages for malicious prosecution, and may be for defamation (if that happens because of her false complaint to police), against the complainant. But that is something to be thought much later, and at that stage, you are advised to consult a lawyer after acquittal judgment.
Hope this helps.
