Patna: Tausif Khan, the 35-year-old engineer arrested for plotting the serial blasts in Gujarat’s Ahmedabad city in 2008, was caught after a cyber cafe owner reported him for a social media post, a top Bihar police officer said on Thursday. The cyber cafe owner in Gaya town, 100 km from state capital Patna, had spotted the prime suspect uploading what he felt was an "objectionable’ post and alerted the police.
