Delaware State Police say a man has been charged with his seventh drunken driving offense after authorities say he left a crash scene and drove the wrong way on a highway.

Troopers say 47-year-old Robert A. Hynes Jr. of Wilmington was involved in a crash on Coastal Highway early Thursday while driving under the influence of alcohol. Troopers say he has six prior convictions for DUI.

Hynes had a valid driver's license when he was arrested.

He is being held on $51,500 secured bond. State police do not know if he has a lawyer.
