Veteran journalist Arulldas Sinnappan feared for the lives of his family members - a wife and two children - while he was investigating the mass graves of Wang Kelian in Perlis.

He managed to expose the mass deaths linked to human trafficking in May 2015 when police discovered 139 graves, 106 bodies, believed to be Rohingya, and 28 illegal immigrant detention camps located deep in the jungles of Bukit Genting Perah and Bukit Wang Burma.
