NAIROBI (Reuters) - Ethiopia’s attorney general said on Monday that a five-month long investigation into procurement processes at the huge military-run conglomerate METEC has revealed vast corruption.

“For six years METEC made international procurements totaling $2 billion without any bidding processes,” Berhanu Tsegaye told a news conference after announcing the arrest of several dozen security officials.

In August the government ousted METEC from a $4 billion dam project on the River Nile due to numerous delays in completing the project.
