COLLEGE PARK, Md. (AP) — A Prince George’s County police officer convicted of beating a University of Maryland student during a 2010 celebration has had his conviction overturned.

James Harrison was found guilty of second-degree assault in the 2010 beating of a student during a celebration that followed the Maryland basketball team’s win over Duke. Harrison was given a one-year suspended sentence in 2012 and served 30 days of home confinement. But earlier this month, after a reconsideration hearing, a judge overturned the conviction, giving Harrison probation before judgment.

State’s attorney’s office spokesman John Erzen says prosecutors were disappointed that the judge set aside the jury’s verdict. He said the judge gave no reason in ruling.

A telephone message left Wednesday for Harrison’s attorney was not immediately returned.
