Crime in areas patrolled by the Pinellas County Sheriff's Office declined 5 percent last year, according to numbers released by the agency on Wednesday.
The department also reported a drop in "Part 1" crimes, which include homicides, sex offenses, robbery, aggravated assault, burglary, larceny and motor vehicle theft. During 2013, Part 1 crimes decreased 5.8 percent, with an overall five-year decline of 23.8 percent, the Sheriff's Office said.
In 2013, six homicides were investigated by detectives, compared to 17 in 2012. Robberies fell 12 percent and burglary 10 percent.
However, the Sheriff's Office saw a rise in the number of aggravated assaults involving firearms — from 61 in 2012 to 86 in 2013.
Total arrests increased from 12,895 in 2012 to 14,139 in 2013.
The Sheriff's Office numbers reflect a nationwide decline in crime. According to the Federal Bureau of Investigation, all law enforcement agencies "as a whole" reported a 5.4 percent decrease in the number of Part 1 crimes during the first six months of 2013.
The primary service area for the Sheriff's Office is the unincorporated area of Pinellas County and 13 cities under contract with the sheriff for law enforcement services.
