Recall that the ex-SGF was on Wednesday detained by EFCC.

An EFCC source who spoke to Punch said both the personal account of Lawal, and the account of Rholavision Engineering Limited, a company incorporated by the former SGF in 1990, have been frozen by the EFCC.

The source said: “As part of investigations into the former SGF, we have frozen the accounts of his companies which he allegedly awarded a N223m consultancy contract for the removal of invasive plant species in Komadugu, Yobe Water Channels.

“We are also tracing several accounts where monies were paid into and will find out their role in the alleged fraud. No stone will be left unturned.

“The SGF is still in our custody but he is giving us full cooperation.

“The Lawal’s firm was established by Lawal in 1990 for the purpose of ICT and not for agro-business. So, his associates will also explain why they got a contract to cut grass. They will also be asked to provide evidence of tax payment and all other necessary documents.

“Lawal claimed he was no longer heading the company when he awarded the contract to Rholavision but the Bank Verification Number of Babachir David Lawal was still the signatory to Rholavision Engineering Limited accounts and 13 other accounts, some with different names were being controlled by the SGF when he awarded the contracts.”

President Muhammadu Buhari had in October sacked Lawal over alleged irregularities in Presidential Initiative on North-East (PINE) activities.
