Two concerned Ghanaians have reportedly called for an investigation into alleged acts of corruption and abuse of office involving Sulley Sambian, the Acting Chief Executive Officer (CEO), and Dr.

Sulemana Abdulai, the Board Chairman, of the Northern Development Authority (NDA).

According to a report by radiotamaleonline.com, the allegations - raised by an insider informant and a concerned citizen, whose identities have been withheld - focus on suspected improprieties in the sale of state assets, misuse of authority resources, and conflicts of interest by the two officials.

The duo are accused of orchestrating the sale of prime lands owned by the NDA in Tamale, the Northern regional capital, as well as Accra, the nation's capital.
