The accused, identified as Mohrram Ali, a resident of Delhi's Brahmpuri area, allegedly made the calls using a SIM card procured in the name of a relative, whom he wanted to falsely frame. Ali believed that the relative was the reason behind her daughter's disturbed married life, a senior official said.
On Friday, he had called up police, saying he will blow up the departure hall of Terminal 3 at Indira Gandhi International Airport if Kanhaiya was not released immediately.
"Ali was aware of the JNU row and knew what sensation it could create. He also told police that he had been to jail sometime back in connection with a fight with the relative," the senior official added.
