A 34-foot boat carrying 10 people hit an unlit channel marker in the Severn River near the Route 450 bridge about 3 a.m. Saturday, injuring four, police said.
Cpl. Steve Stauffer of the Maryland Department of Natural Resources Police said the four were treated for non-life threatening injuries. Police are investigating the accident, Stauffer said. He said alcohol may have played a factor, but no charges had been filed.
One person was flown to Maryland Shock Trauma Center with breathing difficulties, but was later released, Stauffer said. The 23-year-old operator was treated for a broken jaw at a nearby hospital, he said.
