Yasin was traced and detained at the India–Nepal border in Nepal near Raxaul, Bihar by a team of undercover Indian police on 28 August 2013 following the 2013 Hyderabad blasts. It was a joint operation between the Intelligence Bureau and the Bihar Police. He was the second big catch for Indian security agencies after the arrest of Abdul Karim Tunda, a key Lashkar-e-Taiba operative and expert bomb-maker, who was arrested from the India–Nepal border on 16 August. "He is presently in the custody of Bihar Police. His interrogation is going on", the home minister Sushilkumar Shinde had said at the time.

Indian intelligence sources claim that Yasin Bhatkal entered Pakistan in early 2006 on a regular commercial flight from Dubai even though he did not have a visa and was whisked away from the aircraft by his contacts to avoid immigration checks. Yasin was taken to a hilly region with little habitation around, about 8–10 hours from Karachi and believed to be somewhere in the Pakistani province of Balochistan. "Next day our training started. There were six instructors, who I understand were from Pakistan army," he said after his arrest, adding that he and some other recruits were taught to handle weapons and explosives and make bombs during the training that lasted about 50 days. Yasin has told interrogators that he spent about 50 days in Pakistan undergoing training to launch terror attacks and returned to Dubai in the same manner after his hosts stamped his passport with fake immigration stamps to show that he had entered and exited India.^[7]
