The Gujarat Anti-Terrorism Squad (ATS) on Monday nabbed a man who is believed to have played a key role in smuggling a large cache of heroin into the state from Pakistan through the sea route a few months back.

The accused, Arshad Sotta, was arrested from the Indo-Nepal border, said an ATS release here. Sotta was a key person in smuggling the contraband into Gujarat from Pakistan through a boat, it said. Sotta, a native of Mandvi in Kutch district, is the fourth accused to be arrested by the ATS in connection with a racket involved in selling heroin smuggled from Pakistan using the sea route.
