The police filed a FIR (First Information Report), a day after the Delhi Commission for Women (DCW) wrote to Police Commissioner Amulya Patnaik over the threats to Kaur.
A complaint regarding the online abuse of the Lady Shri Ram College student was forwarded to Commissionar of Police by DCW on Monday. The Deputy Commissioner of Police of the area then spoke to her and provided necessary security, the police said.
Joint Commissioner of Police Dependra Pathak told that the FIR had been filed under section 67 of the IT Act and sections 354 A (sexual harassment) and 506 (criminal intimidation) of the Indian Penal Code.
Kaur complained to the DCW against the online threats she got since taking on the RSS-affiliated Akhil Bharatiya Vidyarthi Parishad.
Kaur posted on her Facebook: "I am a student of Delhi University. I am not afraid of ABVP. I am not alone. Every student of India is with me."
In a series of tweets, the 20-year-old also appealed to others to join the "Save DU" march at the Delhi University campus by students and teachers in huge numbers.
Violence erupted last week after the ABVP students allegedly manhandled and thrashed students protesting the cancellation of an event at Ramjas College at which controversial JNU student Umar Khalid was scheduled to speak.
