Public Prosecutor v Mangalagiri Dhruva Kumar: Drug Trafficking under the Misuse of Drugs Act

In Public Prosecutor v Mangalagiri Dhruva Kumar, the High Court of Singapore heard the case against Mangalagiri Dhruva Kumar, who was charged with trafficking diamorphine under the Misuse of Drugs Act. The prosecution's case relied heavily on the testimony of a single witness, Shanti Krishnan, who claimed the accused supplied her with the drugs. The court, however, found Shanti's testimony unreliable due to inconsistencies and a lack of independent recall. Consequently, the court acquitted the accused, concluding that his guilt had not been proven beyond a reasonable doubt.
