He said the criminal investigation was running concurrently with asset recovery processes to prevent further dissipation of what the law enforcement agencies strongly suspected to be proceeds of crime.
The Deputy-Attorney General said the suspect was also under a second strand of investigation, which was part of a larger international organised crime scheme.
“The Economic and Organised Crime Office (EOCO) is assiduously working with international law enforcement partners on this second strand of criminal investigations,” Mr Srem-Sai said on his Facebook page on Thursday.
Mr Antwi Boasiako, the Ashanti Regional Chairman of the New Patriotic Party, was arrested on Tuesday, May 27, following a summons by the Criminal Investigations Department (CID) of the Ghana Police Service.
He remains in the custody of the EOCO as his legal team continues with efforts to meet his GH₵50 million bail condition.
