Several hours after four students were injured in a shooting at Wilmer-Hutchins High School in Dallas on Tuesday, police said the suspect in the gunfire was taken into custody.

The arrest was announced in a news release from the Dallas Independent School District on Tuesday evening. No other details were provided.

Preliminary information indicated that the shooting was student-on-student violence and not an active shooter situation, multiple sources told ABC News.

The four injured students were transferred to area hospitals, according to Dallas ISD Police Department Assistant Chief of Police Christina Smith, who did not provide more details on their conditions.

During a news conference earlier Tuesday, officials said they had identified the suspected shooter but had not yet made an arrest.
