Rapes reported in UCLA’s jurisdiction doubled in 2016 while reported aggravated assaults tripled, according to an annual crime report issued by the university.

There were 31 alleged rapes reported last year, up from 15 reports the previous year and 25 reports in 2014, according to the 2017 UCLA Annual Security and Fire Safety Report released last month.

Thirteen of the rapes reported last year were said to have occurred in on-campus student housing facilities, the report found. The federally-mandated report covers reported crimes that occurred on university property, affiliated buildings, or public property immediately contiguous to the campus.

“We believe the increase in the number of sexual assault reports is related to increased outreach and educational programs by various entities within the University,” Lt. Scott Scheffler of the UCLA Police Department’s Investigations Division said in a recent email.

“On-Campus Housing, the Dean of Students office, and the Title IX office provide education throughout the school year, and the UCLA Police Department gives presentations to entities such as fraternities and sororities,” he added.

It was not immediately clear how many of the alleged rapes occurred in 2016 and how many occurred in previous years. But Scheffler said Monday that he believes most of those reported last year allegedly occurred the same year.

There were also a significant rise in aggravated assaults, domestic violence, dating violence and stalking, according to the report.

The number of reported aggravated assaults, which involves a clear intent to commit serious bodily injury to another, spiked from 10 in 2015 to 31 in 2016 .

made last year, up from two in 2015. Reports of dating violence surged from one in 2015 to 10 in 2016.

The number of reported stalking incidents jumped to eight in 2016, up from one each in 2015 and 2014.

Information regarding any arrests made or charges filed in connection to these reported crimes was not immediately available from UCLA police officials.

Four hate crimes were also reported on campus in 2016, the report states, including a simple assault “characterized by racial bias” and an act of vandalism “characterized by religious bias.”

The report also makes note of a homicide that occurred on campus in 2016. On June 1 last year, UCLA professor William Klug was shot and killed by Mainak Sarkar, a former student who graduated from the university in 2013, on the fourth floor of the Engineering IV building. Sakar then shot and killed himself. Investigators later located the shooter’s home in Minnesota, where they found the body of his wife, who had also been fatally shot.
