DALLAS – One person is in custody after police received reports of an "active shooter" outside a middle school in Southeast Dallas, but it turns out the suspect didn't have a weapon.

DISD Police Chief Craig Miller said a student at E.B. Comstock Middle School on Hodde Street, just off U.S. 175, called 911 Friday morning and said he felt threatened and that shots had been fired.

An 18-year-old was found on campus, upset over a fight between a family member who attends the school and another student that took place the day before. An officer confronted him and he was taken into custody.

After a search of the suspect and his vehicle, no weapon was found, police said. A DISD officer did pull his gun on the suspect at one point, but no shots were fired and no one was injured.

A woman was also seen in a police squad car in handcuffs outside the school, but her involvement isn't clear.

The scene outside the school showed parents in tears amid recent tragedies at schools.

Just 10 days earlier, 17 people were killed in a shooting at a Parkland, Fla. high school. Earlier Friday, two people were killed in a shooting at Central Michigan University.
