( CNN ) -- The former head of an Air Force sexual assault prevention program was acquitted Wednesday of an assault charge stemming from an incident in Arlington , Virginia , last spring , his lawyer confirmed to CNN . Lt. Col. Jeffrey Krusinski , 42 , was arrested in May and accused of grabbing a woman 's buttocks and breasts in a parking lot in Arlington County , not far from the Pentagon . A police report said the unidentified woman fought off her assailant , who appeared intoxicated . Krusinski was initially charged with sexual battery , but prosecutors later changed that charge to assault and battery , according to CNN affiliate WJLA . `` We are very gratified by the verdict and gratified by the very serious consideration the jury gave to this matter , '' defense attorney Barry Coburn told CNN . `` The system worked , which is always a good thing to see . '' Krusinski , a 1994 graduate of the Air Force Academy who served tours in both Iraq and Afghanistan , was the chief of a branch of the Air Force 's Sexual Assault Prevention and Response Program at the time of the incident . He was removed from that post after his arrest , which came two days before the Pentagon released a report showing a 6 % year-over-year increase in the number of reported sexual assault cases within the military in the fiscal year that ended September 30 , 2012 . Coburn said it was unclear what the acquittal would mean for Krusinski 's Air Force career . CNN 's Larry Shaughnessy contributed to this report .
