Two people were arrested by the police on Sunday night for sending a death threat to Jawaharlal Nehru Students' Union President Kanhaiya Kumar and student activist Umar Khalid. The threat was conveyed through a letter found on Thursday along with a loaded gun in a Delhi Transport Corporation bus operating on a route between the JNU campus and an inter-state bus terminal. The letter threatened to behead the two student activists, who were involved in the controversy surrounding the university in February.

The two accused – identified as Sulabh and Saurabh – were arrested in Delhi under provisions of the Arms Act and charged with criminal intimidation and conspiracy, Additional Deputy Commissioner of Police (New Delhi) Romil Baniya said, adding that a court remanded them in police custody for two days. The Delhi Police had increased Kumar's security after the incident, PTI reported.

Baniya further said that the main accused in the case was Saurabh's elder brother and Uttar Pradesh Navnirman Sena chief, Amit Jani. Jani, who had earlier threatened to kill Kumar in a Facebook post, is believed to have written the threat letter. Sulabh and Saurabh were allegedly the ones who left the letter and the gun in the bus. Police are conducting raids in the Delhi-National Capital Region to apprehend Jani, who reportedly went underground on Friday.
