A 17-year-old boy was arrested after he was found with a BB gun at a Charles County high school, authorities said.
Wednesday at about 9:45 a.m., a tipster reported to Crime Solvers seeing a student with what appeared to be a handgun in a classroom at Thomas Stone High School in Waldorf. Deputies found a BB gun in the suspect's coat pocket, and they also found that the suspect was in possession of a box cutter razor knife, according to the Charles County Sheriff's Office.
The teenager was charged with carrying a weapon on school property, authorities said, and was released into parental custody.
Charles County Public Schools spokeswoman Katie O'Malley-Simpson said parents received an email about the incident and that, generally, students who are caught with a gun could receive a suspension or an expulsion.
