On July 17, 2009, an 18-year-old boy walked into the lobby of the JW Marriot hotel in the Indonesian capital Jakarta and blew himself up. Five other people died in the attack and many more were injured.

The Indonesian police quickly identified the bomber as Dani Dwi Permana - a teenager with no prior criminal record or history of violence. So what could have driven him to commit such an act?
