PAHALGAM, May 25 -- Even as the NIA has filed a comprehensive chargesheet in the Pahalgam terror attack, investigators are aggressively tracing a global supply chain to determine how a US-manufactured GoPro camera supplied to China ended up in the hands of Lashkar-e-Taiba (LeT) terror outfit, senior officials said on Sunday.

The high-tech camera recovered from the terrorists, who were neutralised in an encounter in Dachigam forests last July following the attack, has opened a critical new line of inquiry into the external logistics network supporting terror outfits in Jammu and Kashmir.

Terror groups in Jammu and Kashmir have increasingly been using cameras to record their ambushes for propaganda and psychological warfare.
