The number of reported sex offenses, motor vehicle thefts and liquor law violations at the University of Hawaii at Manoa declined in 2015 from the previous year while the number of drug-related violations on campus significantly increased.

The findings, detailed in the university’s annual security and fire safety report released on Friday, suggest a relatively safe campus on which the most frequent incidences of misbehavior are self-directed.

The report is mandated by the federal Jeanne Clery Disclosure of Campus Security Policy and Campus Crime Statistics Act of 1965.

Liquor law violations that were referred for disciplinary action declined to 884 in 2015 from 932 in 2014. All but two of the violations occurred in campus residence halls, according to UH.

Over the same span, however, drug-related violations that were referred for disciplinary action increased to 509 from 417. All but seven of the violations occurred in campus residence halls.

This was the second consecutive year the total number of cases has increased.

Drug-related violations include those tied to the production, distribution or use of controlled substances and related paraphernalia; and the unlawful cultivation, manufacture, distribution, sale, purchase, use, possession, transportation or importation of controlled drugs or narcotic substances.

According to the UH-Manoa Department of Public Safety, overall forcible sex offenses declined to six in 2015 from eight in 2014. However, within that category the number of rape cases increased from two to three while the number of forcible fondling incidents declined from six to three. The subcategories were introduced in 2014.

Overall, forcible sex offenses on campus have been in decline, from 12 in 2011, to 11 in 2012, to eight in both 2013 and 2014.

Other gender-violence-related offenses — including domestic violence, dating violence and stalking — remained relatively stable.

Domestic violence cases dropped to three in 2015 compared to four the previous year. Dating violence cases increased to eight from six in 2014. There were nine incidents of stalking in 2015 compared to eight the year before.

UH-Manoa has tracked gender-violence-related offenses since 2013.

Motor vehicle thefts, which include thefts of mopeds, dropped to 32 in 2015 compared to 41 the previous year.

The decline follows a surge in 2013, when 49 motor vehicle theft cases were reported compared to just 19 and 16 the previous two years, respectively.

Burglary cases increased to 12 in 2015 from nine in 2014, yet remained far below the annual average of 62 cases reported between 2011 and 2013.

There was one incident of robbery on campus in 2015, matching the total from the previous year.

Aggravated assaults have declined steadily over the last five years, from 16 in 2011, to 11 in 2012, to five in 2013 and just one in 2014. Last year, there were no reports of aggravated assault on campus.

According to the UH Institutional Research Office, 18,865 students were enrolled at the UH system’s flagship campus in fall 2015. The campus area covered in the annual security report spans 320 acres and 278 academic, administrative, residential and recreational buildings.
