Gulzar Imam, the founder, and head of the outlawed Baloch Nationalist Army is a "high-value target" in the eyes of the military.
The army reported that a "high-value target" was captured by Pakistan's top intelligence agency during an operation against a Baloch rebel organization in the southwest of the nation.
Gulzar Imam, better known as Shambay, is the founder and commander of the outlawed Baloch Nationalist Army, according to a military statement released on Friday.
The Baloch Republican Army and United Baloch Army combined to form the BNA, an umbrella organization for Baloch insurgents.
The BNA, according to the army, was responsible for several "terrorist" attacks on security personnel around the nation.
Shambay's trips to India and Afghanistan are documented, according to the military's propaganda wing, and his alleged connections to adversarial intelligence agencies are under investigation.
The military provided no other information beyond stating that the arrest was made possible by months of intelligence work.
Baloch separatists have been in an uprising in the gas-rich southwest Balochistan region near the borders of Iran and Afghanistan for more than 20 years.
Baloch nationalists at first sought a piece of the provincial wealth before starting a push for total independence.
