The commission also confirmed reports that Musiliu Obanikoro, a former minister of state for defence, returned N100 million.
According to NAN, Wilson Uwujaren, EFCC spokesman, disclosed this via a SMS.
Dikko, who headed the NCS between August 2009 and August 2015, was reportedly arrested by the EFCC in June over alleged diversion of N40 billion from the agency’s coffers.
He was said to have been released due to his poor health and was expected to return more money.
Uwujaren confirmed the seizure of a property belonging to the former customs boss in the Jabi District of Abuja, saying it was under investigation.
There were reports that the property – a mansion located at 1 Audu Ogbe Street, Jabi, Abuja – worth N2 billion.
Uwujaren said Obanikoro also dropped his international passports.
“He dropped his Nigerian and American passports, apart from being released to two sureties,’’ Uwujaren said.
Obanikoro was released on Friday after spending 18 days in custody.
He is being accused of a N4.7 billion fraud, also linked to his two sons, Jide and Gbolahan.
