Tracy Haynes, 17, was booked into Dallas County Jail at 9:32 p.m. and is facing a charge of aggravated assault mass shooting. The arrest came after four students were injured in a school shooting Tuesday afternoon, about a year to the day when gunfire erupted on the same campus.

The chief of police for the Dallas Independent School District says the student who shot four students when he opened fire at a Dallas high school this week was in and out of the building in less than two minutes and is believed to have been targeting a specific student.

Dallas police responded just after 1 p.m. to a shooting incident reported at Wilmer-Hutchins High School, located at 5500 Langdon Road. One student told CBS News Texas that she heard seven gunshots. Authorities confirmed at around 2:20 p.m. there was no active threat and that the school campus had been secured.
