Mohammed Shariful Islam Shehzad, arrested for allegedly attacking Saif Ali Khan, crossed Meghalaya's Dawki river to enter India about seven months ago, a preliminary probe has reportedly found. He used West Bengal resident Khukomoni Jahangir Sekh's Aadhaar card to get a SIM card after failing to procure an Aadhaar for himself. He came to India to look for employment.
