A student was stabbed inside Bladensburg High School on Wednesday, police say.
The student was cut in the face and taken to a hospital with injuries not believed to be life-threatening, police said.
Witnesses told News4 the attack occurred inside a bathroom at about 1:30 p.m.
The suspect is at large, Cpl. Kyndle Johnnson said live on News4. The motive is unknown, she said.
A school resource officer is assigned to the school. Additional information was not immediately released.
Earlier Wednesday, two high school students in Annapolis were hurt in a stabbing and fight. Seven students face charges.
Anne Arundel County police thanked school resource officers at Annapolis High for disarming the student who had a knife.
“The SROs really potentially could have saved a lot more trauma and injury at the school,” she said.
A number of communities in the D.C. area have opted to withdraw SROs from schools for the 2021-2022 school year, a review by the News4 I-Team found. Others increased their forces and pledged to further bolster their programs.
