Sixteen major crimes were reported in Papua New Guinea's capital Port Moresby between Christmas and last Friday.
The newspaper The National reports the capital's Metropolitan Superintendent Perou N'Dranou saying the crimes included two armed robberies, six stolen vehicles, six sexual assaults and one attempted murder.
Mr N'Dranou said car thefts had decreased with police now receiving only about one report of a stolen vehicle each day as opposed to the usual three.
He said he remained concerned by the frequency of sexual assaults which had not decreased since he took office last year.
However, he said Christmas-New Year period was rather quiet for police either because a lot of people had gone away for holidays or there was a bigger police presence on the streets.
