Government has directed the Bureau of National Investigations (BNI) to investigate the circumstances that led to a substance suspected to be cocaine and handed over to an Accra Circuit Court turning into sodium bicarbonate.A statement signed by the Information Minister, John Tia said the BNI has seven days to submit its report on whether the substance handed over to the court by the Police in September 2011, and which has since been in the custody of the court, is the same substance that was later presented to the Ghana Standards Board for testing.The statement said: “Government remains committed to the fight against narcotics, noting that any person found to have played a role that infringes on the law in this matter will be severely dealt with in accordance with the law.”
