Captured Pakistani militant Mohammad Naved told interrogators that he came across the LoC to India nearly two months ago through the Kupwara sector, sources said Thursday.
This is different from his earlier confession that he reached India 12 days ago through the Poonch sector, sources connected to the investigation told Hindustan Times.
Sources also said he stayed with the locals in Kupwara, where youngsters have been readicalised over the past few years.
Naved is also likely to have done a recce of the Samroli area, where he and accomplice Momin ambushed a BSF convoy on Wednesday killing 2 BSF jawans and injuring 14 others.
They were provided weapons by locals in Kupwara and boarded a truck which stopped near Kud on Tuesday evening, about 10 kms from the site of the attack. On the morning of the attack the truck dropped them near Narsu.
Naved is being questioned at the joint interrogation centre (JIC) in Jammu. A team from the National Investigation Agency, which possibly includes officials who served in the state is headed to Jammu. A special team from the intelligence bureau is also likely to join the interogation.

Naved was questioned all night on who his handlers in Pakistan were and on the route he took to cross over to India.
The militant from Faisalabad was captured on Wednesday, shortly after he and accomplice Noman alias Momin attacked the convoy. Noman was killed in retaliatory fire by BSF personnel.
A resident of Ghulam Mohammadabad in Faisalabad, Naved, believed to be in his early 20s, has two brothers and one sister. Initially, he said he was in his early 20s, but later changed his age to 16.
Is Pak militant Naved a juvenile, or is he just being clever?
