The rate of violent crime at the University of California, Davis, decreased slightly in 1991 but there was an increase in the number of property crimes committed on campus last year. The findings are part of a report prepared annually by the University of California Police Department on reported crimes at UC's nine campuses and the Lawrence Berkeley Laboratory. Campus crime is counted through the FBI's Uniform Crime Reporting Program, the same program used by law enforcement agencies throughout the state to count crimes. Data from the Davis campus and its medical center in Sacramento showed that violent crime, including homicide, rape, robbery and aggravated assault, represented just under 1 percent of all crimes committed, the second lowest in the UC system. Two rapes and four attempted rapes were reported last year. In 1990, two rapes occurred and one was attempted; and in l989 UC Davis police reported that one rape and an attempted rape occurred on campus. Three robberies were reported last year, down five from 1990 and down three from 1989. All occurred at the medical center. No weapons were used in any of the robberies. Eleven aggravated assaults were reported last year, the same number as in 1990, with 15 reported in 1989. Six occurred on the main campus and five at the medical center in Sacramento. Three of the cases involved the use of weapons. No firearms were used. All property crime, which includes burglary, arson and theft of such items as motor vehicles and bicycles, increased 13 percent. Burglaries decreased by 31 percent at the medical center and 11 percent at the main campus. Auto thefts were at an all-time high of 62, an increase of 100 percent from a year ago. Eleven arsons were reported in 1991, an increase of five cases over the previous year. Most had minimal property damage. Bicycle theft continues to plague the Davis campus, according to Bill Essex, UC Davis police chief. Last year more than 1,000 bicycles were reported stolen, the largest number in any single year at Davis. Drunk driving arrests increased for a second year as a result of UC Davis police officers' participation in specialized training seminars on recognizing driving under the influence of alcohol or drugs. Two hundred and eighteen DUI arrests were made last year, a 52 percent increase over the previous year. For all offenses committed during the year, UC Davis police officers arrested 820. The department's patrol division has been strengthened this year by the addition of two bicycle officers who patrol both the main campus and the medical center complex in Sacramento. The bike officers can, in some cases, respond more quickly to incidents because of enhanced maneuverability. Faculty, staff and student requests for assistance from the crime prevention unit have steadily increased. More than 100 campus departments are working with the unit to develop procedures for handling criminal incidents that may occur. In addition, crime prevention classes for residence hall students provide information on how to avoid sexual assault. Ongoing programs at the medical center in Sacramento are routinely updated and provide information to students and employees about the emergency phone network and the escort program. "Statistics continue to suggest that, while crime does occur on campus and at the medical center in Sacramento, the rate of both violent crime and property crime continues to be lower than in the communities that surround us," said Essex.
