The appellant police officer appealed his conviction and sentence for unlawful or unnecessary exercise of authority after striking a prisoner during fingerprinting.
The appellant argued he anticipated an imminent assault and acted in self-defence.
The Commission upheld the presiding officer's finding that there were no reasonable and probable grounds to believe an assault was imminent, relying on the uncontradicted evidence of another officer present.
The appeal against the conviction and the sentence of forfeiture of four days off was dismissed.
