Teenage girl is grazed in head by stray bullet after shooting at DC's Dunbar High School

A student was struck in the head by a stray bullet following a shooting at a school in Washington DC.

The 17-year-old girl was grazed by the bullet which came in through the window at Dunbar High School, according to police.

She suffered non-life-threatening injuries and the school has been placed on lockdown following the horrific incident. 

Authorities said several rounds of bullets came through the window at the time the student was hit.

The 17-year-old girl was inside the school when she was struck by a bullet shot outside the gate. 

She was taken to hospital with non-life-threatening injuries and Dunbar High School was immediately placed under lockdown. 

The Metropolitan Police Department believe there was an exchange of gunfire outside but do not know the reason behind it. 

They added that there is no active threat inside the school.

James Boteler, commander of the third district, said people were in the area at the time of the shooting and hope people come forward with information.
