The Vice President John Mahama has directed the Inspector General of Police to initiate an investigation into the circumstances surrounding a missing cocaine exhibit.The exhibit tendered in as evidence in court turned into sodium bicarbonate under controversial and mysterious circumstances.The suspect under prosecution over the said cocaine has thus been acquitted and discharged.The police and court officials have since been playing the blame game with each institution trumpeting its own integrity and blaming the other for the mysterious swap.It is not the first time such an incident has occurred. In 2007, cocaine exhibits locked up at the Police Headquarters was also swapped with powdered Kokonte.At a ceremony to present patrol vehicles to the police administration, the Vice President said a thorough investigation must be conducted to bring all perpetrators to book.The Police Administration is scheduled to organize a press conference to officially react to the missing exhibit.Joy News’ Jefferson Sackey who is attending the conference lamented the two hour delay in the start of the conference but said prior information he had picked up indicated the police would not take responsibility for the swap.The police administration had earlier argued that at the time the exhibit was sent to the court, it was verified to be cocaine and cannot therefore be responsible for the exhibit turning into washing powder.
