The civil engineering student from Thane who joined the Islamic State in Iraq before returning home two weeks ago has drawn a detailed picture for interrogators of his life as a jihadi fighter, including valuable information on the group's tactics and strongholds, and how he was recommended for recruitment by a feared red-bearded commander popularly known as 'Omar the Chechen'. Areeb Majeed, who is currently being detained by security officials at a secret location in Mumbai, has also claimed that there was a fifth youth who wanted to join the original group of four that left Thane for Iraq but dropped out virtually at the last minute.
