Gladys Jung Elementary School Principal Christopher Carmichael has been arrested by the FBI.

In a release, the FBI says on Tuesday night Carmichael was arrested by the FBI's Child Exploitation Task Force, the Bethel Police Department, and the Alaska State Troopers.

According to the Lower Kuskokwim District Superintendent Daniel Walker, he got a call last night from the FBI about the warrant. When they arrived, they took multiple forms of digital media. Walker said it was the first anybody had heard of it.

According to Walker, Carmichael has worked in the district since 2000 and has been the principal of Gladys Jung since the 2014-2015 school year.

He said the whole thing has taken the community off-guard.

"People are shocked right now and we don't know what charges are being filed so we don't know how to react beyond that," he said over the phone.

Law enforcement says Carmichael is currently in custody, and the U.S. Attorney's Office for the District of Alaska expects formal charges to be filed Wednesday or Thursday.

As of 3:30 p.m., no charges had been filed in the US Court for the District of Alaska.

The investigation is ongoing.

The Gladys Jung Elementary School website now names Joshua Gill as the acting site administrator.
