A teenager in Baltimore County was arrested Saturday for possession of a handgun and homemade explosives, which he said he was planning to use to kill people at his high school Monday, authorities said.
The weapons were found at the home of Sash Alexander Nemphos, 16, when police were interviewing him about a series of thefts from automobiles, police told the Washington Post.
Cpl. John Wachter of the county police said that Nemphos had brought the gun to school in his backpack Friday and that he told police over the weekend that he planned to use the gun to harm people at school Monday. Instead, he was arrested and held without bail.
Nemphos is a 10th-grader at George Washington Carver Center for Arts and Technology, a public school in Towson, police said.
He was charged initially as a juvenile, then charged Monday as an adult with possession of a handgun and a destructive device and three theft counts.
