A Georgia police officer resigned from his job on Friday after erroneously pulling over a teenager, causing her to spend more than two weeks in a federal immigration jail, and leaving her facing deportation.

The officer, Leslie O’Neal, was employed at the police department in Dalton, a small city more than an hour north of Atlanta.

His arrest of college student Ximena Arias-Cristobal not only led to a domino effect that could lead to her deportation – it also engendered anger and criticism, especially given the circumstances of her immigration-related detention.
