A near-tripling in the number of rapes and significant increases in burglary and larceny in 1985 helped give the city its first rise in major crimes in four years.
Reported major crimes increased by 25% last year, reversing a three-year trend of declining crime incidents, according to Police Chief Neil Purcell.
Rapes increased from four in 1984 to 11 last year, while larceny incidents jumped 31%, from 490 to 644.
Burglary reports rose almost 18%, and aggravated assault increased by about 26%, a Police Department report said.
Purcell said he was "not really disappointed" with last year's crime statistics because the actual numbers of crimes are still low.
He also said that crime was increasing throughout the south county.
"San Clemente had a similar increase, Newport Beach went up by 12%, Irvine by about 6%," Purcell said. "Compared to other cities in the county, I think we're holding our own. For the amount of activity generated in this city and the size of the force, I don't foresee a bleak picture."
