Jungle justice or mob justice is a form of public extrajudicial killings which can be found in Nigeria and Cameroon, where an alleged criminal is publicly humiliated, beaten and summarily executed by vigilantes or an angry mob.^[1][2][3] Treatments can vary from a "muddy treatment", where the alleged criminal is forced to roll in mud for hours^[4] to severe beatings followed by execution by necklacing. This form of street justice occurs where a dysfunctional and corrupt judiciary system and law enforcement have "lost all credibility. European principles of justice have likewise become discredited."^[5][6]

Notable examples include the Bakassi Boys^[5] and the Aluu four lynching.
