Police arrested a Pak-trained terrorist and three accomplices last night and seized highly-sophisticated explosives like RDX and PETN besides detonators and timers, Director General of Police, Punjab, P C Dogra said today.

Addressing a press conference here, Dogra said BKI member Kulwinder Singh, who received training from the inter-services intelligence of Pakistan, was arrested from Phillaur after he had crossed an unfenced stretch of border in Ajnala sub-sector of Amritsar district. The terrorists were in the process of raising logistics to target several VIPS, including Advani, Thackeray and former Punjab police chief K P S Gill. Preliminary interrogations revealed that they were ``desperate'' to go for Advani because of his ``pro-active'' approach in curbing ISI-sponsored terrorism in Jammuand Kashmir, north-eastern states and coastal states of Tamil Nadu, Gujarat and Maharashtra.

Dogra said while Kulwinder Singh along with his accomplices Darshan Singh and Jagjit Singh were intercepted near Phillaur last night, Karnail Singh, an associate of top smuggler Bakshish Singh Shisa, was arrested later.
