Two people stopped to try to help 26-year-old Ardonas Gilbert, who was running naked along the southbound lanes of Interstate 95 on Monday night, but he allegedly cursed at them and punched them, Delaware State Police said.
Gilbert then ran into traffic, causing three separate accidents as motorists tried to avoid him, police said. No one was seriously injured.
Gilbert was charged with two counts of assault and a single count of being drunk on a highway.
He remained in custody Wednesday. Officials of the Court of Common Pleas in New Castle County said he did not yet have an attorney to speak for him.
