A patrol party of the BSF's 79th battalion, deployed to guard the Indo-Pak border, apprehended the three fishermen from the "vertical area of the Harami Nala creek," a senior official said.
The men have been handed over to the local police, the official said.
The incident comes at a time when a high-level delegation of Pakistani Rangers is in India for bi-annual talks with the BSF.
Given the sensitive nature of the area, even Indian fishermen are barred from fishing in the creek. However, Pakistani fishermen often venture into the Indian waters for a catch.
