Chairman Wontumi, the Ashanti Regional Chairman of the NPP, appeared before the CID in Accra following a failed arrest attempt at his residence.
The nature of the investigation remains unclear, but it is believed to be linked to recent political developments.
Wontumi's Kumasi residence became the center of attraction last Friday when state security agencies stormed his house to arrest him.
The New Patriotic Party (NPP) later issued a statement condemning the state's use of security to intimidate its members.
