The number of crimes reported on Kansas University’s Lawrence campus declined for a second straight year, KU police announced Thursday.

Overall, 660 crimes were reported on campus in 2011 compared to 692 crimes in 2010 and 706 in 2009.

Only two violent crimes were reported last year — an aggravated assault and a robbery. The FBI defines violent crime as murder, rape, robbery and aggravated assault.

“We hope to continue the general downward trend in crime on campus, with the support of the university administration, the increased use of video technology and the efforts of the police and security officers who patrol every day,” KU Police Chief Ralph Oliver said in a statement about the statistics.

The number of assault reports decreased from 31 to 17, and burglaries decreased from 67 to 60. The number of thefts reported increased slightly from 199 to 212, which was less than the 230 reported in 2009 and 267 in 2008.

Overall, reports of crime on campus were down 26 percent since 2001 when 890 crimes were reported.

Oliver said KU recently installed signs on campus indicated that security cameras were in use, and he said cameras helped police find suspects in crimes, including a man accused of peeking at women who were showering at residence halls and three auto burglars operating in the parking lot outside Gertrude Sellards Pearson Hall. KU is also increasing the number of security cameras on campus, Oliver said.
