Officials of the Department of State Services (DSS) have taken in key officials of the Nigerian National Petroleum Corporation into custody.
Many of its top officials have been grilled many time by the NNPC.
A report notes that Ian Udoh, a group executive for refining and petrochemicals has been questioned 11 times since the end of May.
He said there is a “siege mentality” in the corporation at the moment and that pressure has been dominating management meetings of the organisation.
“The DSS has been harassing some of us… There is a siege mentality here at the moment,” he Udoh told Reuters.
The corporation, which has been enmeshed in corruption allegations over the years, the most recent and which as refused to be doused is the over $20 billion allegedly siphoned.
