A University of Alabama associate professor was arrested Tuesday on child pornography charges.

James Andrew Crank, 45, is charged with two counts of possession of material containing visual depictions of persons under the age of 17 involved in obscene acts.

The arrest was made by the West Alabama Human Trafficking Task Force. Investigators carried out a search warrant at Crank’s home Tuesday morning.

Efforts to reach the university for comment were not immediately successful.

Authorities said the warrants against Crank were the result of an ongoing investigation. Devices seized during the search could lead to additional charges.

The Tuscaloosa Police Department’s Cyber Intelligence Unit and the Tuscaloosa County Sheriff’s Office’s K-9 Unit assisted in the investigation.

Crank is being held in the Tuscaloosa County Jail. Bond will be later set by a judge.

According to the University of Alabama’s website, Crank is an associate professor of American literature and culture and director of graduate studies in the College of Arts & Sciences Department of English.
