Nigeria, Feb. 25 -- An Economic and Financial Crimes Commission (EFCC) witness has refuted the suggestion of detaining one of former National Security Adviser Sambo Dasuki's co-defendants in an underground cell during investigations in 2015.

Michael Adariku, an assistant commander 2 at the EFCC, testified on Wednesday at the FCT High Court in Abuja where Mr Dasuki and his co-defendant, Aminu Baba-Kusa, are facing prosecution on charges of diverting N33.2 billion in arms and security funds.

The prosecution specially called Mr Adariku as a witness to debunk a claim that EFCC obtained several statements from Mr Baba-Kusa under duress during his detention while investigating the arms funds diversion case in 2015.
