On interrogation, he identified himself as Hashim. He had come to India in 2008 and married a local girl in 2009. He was arrested after his visa expired in 2010, but was later released on bail, they said.
He had been working as a security personnel at an industrial unit in nearby Sidkul area and apparently entered the campus for employment at BEG.
