Waxhaw's mayor has been charged with driving under the influence in South Carolina.
Autumn Daune Gardner, 37, was arrested early Thursday in Lancaster County, according to law enforcement records.
The S.C. Highway Patrol stopped her about 2 a.m. on U.S. 521 in Lancaster, about 2 miles north of Waxhaw Highway, Observer news partner WCNC reported.
A Lancaster County jail employee said Gardner was released around 8:30 a.m. Thursday.
Gardner did not immediately return phone messages seeking comment.
A former president of the Waxhaw Business Association, Gardner owns a small graphic design firm, Creative Plus, near downtown Waxhaw, a rapidly growing southwestern Union County town of about 3,500.
In November 2006, she was a candidate for interim town manager after Martin Irvine resigned unexpectedly.
In 2007, she defeated incumbent Mayor Gary Underwood, 649 to 371, in her first campaign for elected office. She campaigned on comprehensive town planning, better communication with residents and more transparency in government.
