HOUSTON, April 16 (Xinhua) -- Four students were injured on Tuesday in a shooting at Wilmer-Hutchins High School in Dallas, Texas, local authorities said.

A suspect involved in the shooting was detained on Tuesday evening, according to the police. The identity of the shooter and the motive behind the attack have not yet been disclosed.

Among the injured, aged 15 to 18, three sustained gunshot wounds, said Dallas Fire-Rescue officials, adding that the conditions of the injured range from serious to non-life-threatening.

"Today as we all know, the unthinkable has happened," said Dallas Independent School District Superintendent Stephanie Elizalde at a press conference. "And quite frankly, this is just becoming way too familiar, and it should not be familiar."

In April 2024, a student was shot in the leg in a classroom after another student brought a gun to Wilmer-Hutchins. ■
