The University of Iowa is reporting a sharp increase in alcohol-related arrests over last year, while total arrests are on the decline at Iowa State and UNI. The information is contained in a report released Thursday by the state Board of Regents.

The document shows the University of Iowa reported 534 arrests for liquor law violations between January 1 and September 30 of this year. That compares to just 47 arrests over the same period in 2009. There have been nearly 1,200 total arrests, including those related to alcohol, at the UI this year – nearly double (644) the arrests over the first three-quarters of 2009.

University of Iowa officials credit an increased enforcement effort targeting underage and binge drinking. An ordinance that took effect in June bans people under 21 from Iowa City bars after 10 p.m. The age limit had been 19.

The number of arrests and offenses at the University of Northern Iowa and Iowa State University have decreased from 2009 to 2010. At ISU, 307 people were arrested for violating liquor laws through September of this year. That’s down from 323 in 2009. At UNI, there were just 7 arrests for liquor law violations compared to 11 the previous year.
