41 police officers in Papua New Guinea's capital, Port Moresby, have been suspended in the past three months.
The National Capital District Police Metropolitan Superintendent, Benjamin Turi, says the officers have been suspended for a range of brutality and misconduct charges.
He says they face 89 charges altogether, including three officers who were last week arrested for sexual assault.
Mr Turi told the newspaper, The National, that the force has a problem with brutality and he is committed to removing bad officers and ensuring they are disciplined.
Meanwhile, the prime minister, Peter O'Neill, says 2016 will be a year of police reform, with his government committed to ridding the force of rotten apples.
