FORT CAMPBELL, Ky. — The manager of the sexual assault response program at Fort Campbell, Ky., was arrested in a domestic dispute and relieved of his post, authorities said Thursday.

Lt. Col. Darin Haas turned himself in to police in Clarksville, Tenn., late Wednesday on charges of violating an order of protection, and stalking. Master Sgt. Pete Mayes, a spokesman for the Army post on the Tennessee-Kentucky line, said Haas was immediately removed as manager of a program meant to prevent sexual harassment and assault and encourage equal opportunity.

Haas and his ex-wife have orders of protection against each other, Mayes said. The two are involved in a child custody fight, Clarksville Police Sgt. Chuck Gill said.

Haas was held for a required 12 hours and released.

His ex-wife told police he repeatedly contacted her Wednesday night despite the protective order, Gill said.

Haas is due to retire from the Army soon, Mayes said.

A working phone number for Haas could not immediately be found Thursday evening, and he did not immediately respond to a message sent through what appeared to be his Facebook page.

Allegations of sexual assault in the military have triggered outrage from local commanders to Capitol Hill and the Oval Office. Last week, an Air Force officer who headed a sexual assault prevention office was himself arrested on charges of groping a woman in a Northern Virginia parking lot. President Barack Obama pledged Thursday to “leave no stone unturned” in the effort to halt the abuse, which he said undermines the trust the military needs to be effective.
