The Economic and Organised Crimes Office (EOCO) has opened formal investigations into dealings and transactions of Ibrahim Mahama, brother of former President John Mahama.

Ibrahim Mahama, who heads private engineering firm, Engineers & Planners, was on Tuesday, April 18, 2017, picked up by EOCO for allegedly issuing dud cheques to the Customs Unit of the Ghana Revenue Authority.

He was reportedly interrogated for over eight hours by investigators but was later released.

Joy News sources say he is required to report regularly to EOCO as investigations continue.

However, this is not the first time EOCO investigating the former President Mahama’s brother.

In February, Ibrahim Mahama and a close associate of the former National Democratic Congress (NDC) administration, Ali Seidu, were hauled before EOCO over the corruption scandal that hit the Ghana Cocoa Board (COCOBOD).

The two businessmen were summoned as part of a probe into the activities of sacked CEO of the COCOBOD, Dr. Stephen Kwabena Opuni.

EOCO’s initial investigations are believed to have fingered the two in some deals at the organisation managing cocoa purchase and production in Ghana.

Ibrahim Mahama's company was contracted under the erstwhile NDC government to execute various projects, notable among them being the construction of a platform for the AMERI power plant.
