A Charleston police officer was rushed to a hospital with injuries after crashing a squad car on Johns Island early today, authorities said.

About 12:30 a.m., the off-duty officer was traveling west on Main Road near St. Johns High School in a 2007 Crown Victoria when the vehicle went off the right side of the road and into a ditch, said Cpl. Bob Beres of the S.C. Highway Patrol. The driver over-corrected, drove over to the left side of the road and struck the ditch.

The officer, 31-year-old Sarah Fortier, was taken to Medical University Hospital with injuries, Beres said. He did not have any information about her condition.

She was charged with driving under the influence, Beres said.

Charleston police spokesman Charles Francis said Fortier has been placed on administrative leave without pay.

The collision is under investigation by the Highway Patrol.
