A shooting in Northeast D.C. Wednesday made at least one bullet fly into a classroom and led to a crash that shut down power for dozens of residents.

Police say it began with a dispute between two people in two different cars who were chasing each other. They fired shots near Aiton Elementary School on 48th Place NE, police said.

One of the bullets flew into an empty classroom and the school was put on lockdown.

"They shut the windows and locked the doors, pulled the shades and had the kids sit on the floor," parent Shelly Imes told News4.

Imes' son attends the school.

"He's 4 years old so he just thought they was playing a game," she said.

"Students were on a field trip, and while the classroom was empty and no one was harmed, we approach situations like this with extreme caution," Principal Malaika Golden said in a letter sent home to parents.

"I'm tired of it. I'm tired of it," Imes said.

A short time later, there was a violent crash on 49th street.

One car involved in the shooting sped into a small park and struck the guide wire to the power pole, snapping the pole in half and bringing live wires down.

"I have no electricity," resident Dora Thomas said.

Forty-two Pepco customers in the neighborhood are without power.

The driver of the car was arrested, police say. The second driver involved in the shooting is still at large.
