According to BBC, he was arrested from the south-eastern Kishtwar district.
BBC further said quoting the police that Ahmad had returned recently from Pakistan via Nepal and was “recruiting youth for militant attacks”.
The hijacked plane was flown to Kandahar in Afghanistan, from where the hijackers negotiated the release of militants fighting in Kashmir.
India had then released three Kashmiri militants in exchange for the passengers. None of the five armed hijackers was caught.
