BETHESDA, Md. — A suburban Washington, D.C., high school is on lockdown and Interstate 270 ramps are closed after police say a man fired a shot at his girlfriend.
Police say the man reportedly fired a shot at his ex-girlfriend about 7:15 a.m. Tuesday in Bethesda, Md. The woman was not injured. All exterior doors at Walter Johnson High School have been locked as a precaution.
County police say a man armed with a high-powered rifle fled in a 2004 black Chevy Tahoe with Maryland license plates.
