According to the statement, the National Security Agency found out that MB member Yehia Mahran Othman played a prominent role in said plot by being one of the main arms of the imprisoned Muslim Brotherhood senior figure Safwan Thabet.

Thabet, Egypt's Juhayna Food Industries’ chairman, was arrested in December of last year over charges of calling for unauthorised protests, joining an outlawed group, inciting violence, and financing a terrorist group.

The agency concluded that Thabet assigned Othman to exploit the former's companies in transferring and concealing the terrorist organisation's funds in an attempt to circumvent the legal procedures taken to freeze its assets, the statement added.

According to the statement, Othman operated out of an apartment in Hadayek Al-Ahram district, where he concealed MB funds.

Police forces raided the apartment and discovered a secret room containing a total of $8.4 million along with an undisclosed amount of money in other foreign currencies and a hidden stash of ammunition, the statement read.

All legal procedures were followed, and the Supreme State Security Prosecution was notified to commence its investigations, the statement concluded.
