The Nigerian Army and Department of State Security (DSS) have discovered an arms store at Effium in Ohaukwu LGA of Ebonyi State.
An intelligence source disclosed on Saturday that a combined team of agents stormed the location of the arsenal.

According to PRNigeria, suspects arrested during the operation have been taken into custody for interrogation and prosecution.

Four persons apprehended during the raid were alleged members of the group, witnessed claimed.
They added that a shrine that served as a protective shield for IPOB and others was uncovered.
When contacted on the discovery of the arsenal by security agents, DSS spokesman, Peter Afunanya, did not confirm or deny the operation.
