"A 25-year-old mentally disturbed person crossed into this side of international border in Basantar river area in Ramgarh sub-sector of Samba district early today," a senior BSF officer told PTI.
"Nothing incriminating was recovered from him," he said, adding that the man was bare-footed and wore just a Pathan Shilwar and Kameez with a sweater.
He was quizzed by several agencies including BSF but nothing suspicious was found from him.
The man is likely to be handed over to the police, he said.
