Police Criminal Investigations Department (CID) says it will investigate how cocaine kept in the exhibit room at its headquarters turned into sodium bicarbonate.This had led to the court acquitting the man who was accused of possessing the narcotic substance.A circuit court judge has therefore directed the Inspector General of Police to as a matter of urgency institute an enquiry into the incident.Director of Operations at the CID, Chief superintendent Frank Kwofie tells Joy News the service will not shy away from any enquiry.“At the time that it was opened at the court, and at the time that it turned into a different substance, needs to be investigated thoroughly and whoever is culpable must be held liable,” Chief Superintendent Frank Kwofie promised.
