The amount of violent crime reported in Los Angeles rose by double digits last year, officials said Monday, a spike that reverses an 11-year streak of falling crime numbers in the city.

Violent crime, which includes rapes and aggravated assaults, rose 14.3 percent last year, Los Angeles Police Department Chief Charlie Beck said at a Monday news conference. The rise in violence comes during Mayor Eric Garcetti’s first full year in office.

Acknowledging a “significant increase” in violent crimes, Beck attributed the rise to three factors: increased accuracy of internal LAPD reporting, more domestic abuse cases and more street fights.

As part of the violent crime spike, the LAPD reported a nearly 21 percent increase in rapes in 2014, compared with the year earlier. There were 924 rapes last year, compared with 764 a year earlier.

Beck referenced an increase in “acquaintance rapes” and mentioned “young people.” He provided no other information on why the city saw more acquaintance rape cases last year.

A breakout of 2014 crime numbers by region wasn’t available Monday, the LAPD said. For the year ending Dec. 27, the San Fernando Valley saw violent crime rise 11.3 percent and gang crime grow 8 percent, the LAPD reported earlier this month. The Valley increase mirrors the citywide trend.

Still, questions remain about whether the city is truly more violent or if the LAPD is merely now accurately reporting violent crimes. The spike in violent crime comes after the Los Angeles Times reported last summer the LAPD inaccurately misclassified more than 1,000 violent crimes as less serious crimes. Since then, the LAPD has changed its reporting approach, Beck has said.

Asked about the inaccurate crime statistics, Garcetti said Monday he would support having an outside audit of crime numbers every few years.

But neither Garcetti nor Beck blamed the rise in crime solely on the LAPD’s inaccurate reporting standards.

“This year went in the wrong direction,” Garcetti said.

To combat the rise in reported domestic abuse cases, Garcetti announced a citywide expansion of the LAPD’s Domestic Abuse Response Teams. The Mayor’s Fund of Los Angeles, an outside nonprofit run by Garcetti’s team, will raise money to pay for the $891,000 expansion.

“The Mayor’s Fund for Los Angeles will take the lead in raising the funds for the expansion,” mayoral spokeswoman Vicki Curry wrote in an email. “We expect a combination of private and philanthropic donations and government grants.”

Beck and Garcetti also repeatedly praised figures that they said showed an overall slowdown in crime compared with some past years. Aggravated assaults are down 40 percent compared with 2005, according to a booklet distributed Monday. Rapes are down 16.4 percent compared with 2005.

Officials didn’t explain why they chose to compare 2014 numbers with 2005’s data.

Property crime also dropped in 2014 by 4.6 percent compared with a year earlier. That category of crimes includes burglary, motor vehicle theft and larceny, which all dropped in 2014, officials said.
