A new report by Papuans Behind Bars (PBB) exposes the Indonesian government’s increased use of arbitrary arrests to shut down protests in West Papua in 2015. The 28-page report ‘Rising voices, rising arrests: A look at West Papua in 2015’ exposes how freedom of expression and assembly in the region remains severely restricted. Based on data and testimonies collected and verified by PBB, the report shows that 1083 Papuans were arrested arbitrarily across Indonesia in 2015. This represents the highest number of arbitrary arrests documented in a single year since comprehensive records began in 2012. 80% of those detained were arrested for participating in or planning peaceful demonstrations.
