Kolhe was killed in eastern Maharashtra's Amravati city on June 21 after sharing on social media a post supporting suspended Bharatiya Janata Party leader Nupur Sharma over her controversial remarks about Prophet Mohammad.
Maulavi Mushfique Ahmad (41) and Abdul Arbaz (23), the two accused arrested by the National Investigation Agency (NIA), were present at a biryani party held to celebrate the killing of Amravati-based pharmacist Umesh Kolhe.
In its FIR lodged in connection with Kolhe's killing, the investigating body termed the crime an act of larger conspiracy to frighten people who are supporting the suspended BJP leader.
