Following British colonialism and with changes and ban in ancient hunting practices, the Anaang witnessed attacks by wild animals. As the men went to fight in World War II these attacks intensified. The British authorities called the attacks murder and blamed it on "the barbarism of the Africans". The Anaang were accused of belonging to a secret society called "Ekpeowo" (The Human Leopards Society). It has been argued that killings born out of insurgency against the British elsewhere in Africa led to the branding of leopard attacks as murders by the British authorities among the Anaang. Between 1945 and 1948 about 196 people were killed in Ikot Okoro community in the present-day Oruk Anam LGA; the Ikot Okoro Police station was set up because of this reason. The British convicted 96 people and executed 77 innocent people. The Anaang religion called Idiong was banned and the priests arrested. Articles and worship materials were publicly burnt and those who did not convert to Christianity automatically became suspects.
