DALTON, GA — A Dalton police officer has resigned following backlash over a traffic stop that led to the detainment of a 19-year-old undocumented woman.

Officer Leslie O’Neal submitted his resignation in a letter on Saturday, according to authorities. The officer came under scrutiny after pulling over Ximena Arias-Cristobal, whose arrest ultimately led to her being held in immigration custody for three weeks.

Arias-Cristobal was released on bond last week and has since reunited with her family.

Dalton Police have not commented further on the resignation.
