(Tempe, AZ) -- Violent street crimes in Tempe are dropping. The city fell from 30 in 2012 to 15 last year. The "Arizona Republic" reports all types of robberies declined by 76-percent during Tempe's Safe And Sober campaign. The event was carried out during the beginning of ASU's new school year. But, data shows there was little progress in reducing sex crimes. Police launched the campaign after data showed violent crime in the city mainly occurred around University Drive, Broadway Road and Rural Road in an area known as the "Loud Party Corridor." A similar version of Safe and Sober is expected to return this fall.
