Former Secretary to the Government of the Federation (SGF) Babachir David Lawal is in the Economic and Financial Crimes Commission detention.
EFCC arrested Lawal on Wednesday, and its operatives have been interrogating the ex-SGF over N200million contract awarded to a company, Global Vision Limited, a company linked to him.
The contract was awarded by the Presidential Initiative for the North East (PINE) for clearing of “invasive plant species” (weeds) in Yobe State.
A presidential panel headed by Vice President Yemi Osinbajo found Lawal guilty of infractions in the award of the contract.
The panel recommended further probe of some of the activities of PINE.
