A team of NIA officials after the encounter had visited the site of Ban Toll Plaza and had recorded statements of the eyewitness and police officers on the same day.

The NIA is also probing the encounter in Nagrota which took place on January 31 this year, in which three terrorists from JeM were killed at the same toll plaza.
