The Air Force officer in charge of a sexual assault prevention unit at the Pentagon was arrested early Sunday morning for sexually assaulting a woman after a night of drinking.

Lt. Colonel Jeffrey Krusinski, 41, was arrested and charged with sexual battery in the very early hours of Sunday morning on the 500 block of South 23rd Street in Arlington, VA.

According to a crime report issued on the incident, a very drunk Krusinski approached a female in a parking lot and grabbed her breasts and buttocks. The victim attempted to fight the Air Force bigwig off when he tried to grope her a second time and then she alerted police, who took Krusinski into custody.

Krusinski was the chief of the Air Force's Sexual Assault Prevention and Response Program. The office that he ran "reinforces the Air Force's commitment to eliminate incidents of sexual assault through awareness and prevention training, education, victim advocacy, response, reporting, and accountability," according to its Web site. "The Air Force promotes sensitive care and confidential reporting for victims of sexual assault and accountability for those who commit these crimes."

A senior defense official told NBC News that Krusinski did not show up for work on Monday and when contacted by colleagues inquiring about the incident he refused to talk about it. An Air Force spokesperson said that Krusinski was removed from his position immediately upon learning of Sunday's arrest and will be barred from his job pending the outcome of an official investigation into the allegations.

Krusinski is currently being held on a $5,000 unsecured bond, according to officials.
