Maryland State Police say a man who was shot by a trooper after throwing large rocks at motorists in Cecil County is facing assault charges.

Police say 50-year-old Clyde S. Patterson III of Perry Point threw rocks at drivers along Route 40 on Tuesday. One motorist said Patterson pulled out a gun. Patterson also threw rocks at two troopers who arrived at the scene.

Police say the troopers stopped traffic in both directions as Patterson walked toward them. He refused to surrender and show his hands, then lunged toward a trooper, who then fired his pistol.

Patterson was served a warrant Wednesday charging him with six counts of first-degree assault and other counts.
