On a tip off about presence of two militants in Chattabal, the special operation group cordoned off the area and nabbed Abu Talib, a resident of Multan, sources said.
The spot where he was picked up from is a little over a km from Bemina area where the terrorists struck yesterday, leaving five jawans dead and seven others injured.
The Pakistani militant opened fire on the SOG personnel with a pistol but he was overpowered and arrested, the sources said.
Sources said the breakthrough was achieved when the intelligence agencies traced a call made by the militant to his handlers in Pakistan soon after the attack yesterday.
Two suspected Pakistani terrorists, disguised as cricketers had on Wednesday stormed a CRPF camp here in a 'fidayeen' (suicide) attack, the first major strike in the city in three years.
