The officer of Indian spy agency ‘Research Analysis Wing (RAW) was arrested during a raid in Balochistan on Thursday.
According to security sources, Kalbhushan Yadav (living in Pakistan with a name of Hussain Mubarak Patel) had entered Pakistan through Balochistan-Iran border.
Intelligence agencies have kept him under detention and his interrogation is underway.
As per his details gathered by the forces, Yadav was born on April 16, 1970 in Mumbai. His father’s name is Sudher Yadav, while his wife and two children also live in Mumbai.
Apart from conspiring to sabotage CPEC, the operative had contacts with banned organizations and was working on the plans to break Karachi and Balochistan away from Pakistan.
Pakistan Foreign Office also protested to India after arresting Yadav, sparking a new diplomatic tiff between the nuclear-armed neighbours.
A foreign ministry statement described the incident as the “illegal entry into Pakistan by a RAW officer and his involvement in subversive activities in Balochistan and Karachi”.
It said the Indian High Commissioner had been summoned by the Foreign Secretary so he could convey his “protest and deep concern”.
Balochistan, Pakistan’s largest but least developed province, has been battling a years-long separatist insurgency that the army has repeatedly claimed is “terrorism” promoted by states hostile to Pakistan such as India.
Karachi, a city of 20 million and Pakistan’s economic hub, is frequently hit by religious, political and ethnic violence.
