Balochistan Home Minister Mir Sarfaraz Bugti confirmed that an "Indian spy" had been arrested from the southern part of the province and he had been transferred to Islamabad.
Bugti claimed the man was sponsoring subversive activities in the already-troubled province and arranging for funding and training of the Baloch Republican Army.
"He has been identified as Bhushan Yadav and his arrest confirms the involvement of RAW" in Balochistan, he said.
Television channels reported that the arrested man was a serving Indian naval officer and deputed to work for India's external intelligence agency RAW.
