Ferozepur/New Delhi, April 25 -- A Border Security Force (BSF) constable, Purnab Kumar Shaw, was detained by Pakistan Rangers on Wednesday after he accidentally crossed the zero line in the Ferozepur sector, officials said on Thursday.

"The jawan inadvertently entered Pakistan territory and was taken into custody. All efforts are on to ensure his safe and early return," said BSF Punjab Frontier inspector general Atul Fulzele.

Two flag meetings between the two forces - one on Wednesday evening and another at 2pm on Thursday - were inconclusive. Part of the 24th battalion, Shaw is a resident of West Bengal.

Shaw was guarding a group of local farmers harvesting wheat across the cobra fence in Mamdot block when he strayed across the border....
