NASHVILLE (AP) — Crime on Tennessee's college campuses has dropped slightly, but a new report by the Tennessee Bureau of Investigation shows the number of assaults to be increasing at the state's institutions of higher learning.

The report released Wednesday by the TBI shows that overall crime on campus decreased by 4.1 percent in 2012 from the previous year. The report says assaults increased by nearly 14 percent last year.

The report shows drug crimes went down slightly and sex crimes dropped by 20 nearly percent.

Theft continues to be the most reported crime on campus, and theft from a building made up about 36 percent of all crimes reported. But the number of thefts from vehicles, which has steadily declined over the years, plummeted more than 33 percent.
