A 35-year-old man who was allegedly behind a series of hoax bomb threats to airports and railway stations across the country has been arrested after he presented himself before Nagpur police, a police officer said on Friday.

Jagdish Shriam Uikey, resident of Arjuni Morgaon in the Gondia district, arrived in Nagpur by flight after the city police sent him a notice seeking his presence for a probe, and surrendered on Thursday, he said.
