Acting on a tip-off, a joint 'naka' (checkpost) of the state police and Army's 62 Rashtriya Rifles (RR) unit was set up near Nagbal, in the Zainapora area of Shopian, said a police spokesman.
He added that during checking, the three LeT OGWs -- Showkat Ahmad Mir, Waseem Ahmad and Junaid Ali Bhat -- were apprehended and three hand grenades were seized from their possession.
During questioning, the three men confessed that they were working at the behest of LeT operative Wasim Shah and were tasked with hurling grenades at police establishments and snatching the weapons of the securitymen in Shopian, said the spokesman.
A case was registered in this regard and a probe was on, said the spokesman.
Earlier in the day, three LeT militants were killed in an encounter with the security forces in the Sopore area of Baramulla district in Kashmir.
