A suspected gunman, believed to be a male student, has been taken into custody after allegedly opening fire on multiple students inside Sante Fe High School in Texas, killing at least eight people.

“This morning an incident occurred at the high school involving an active shooter,” the Sante Fe Independent School District’s website states.

“The situation is active, but has been contained. There have been confirmed injuries. Details will be released as we receive updated information. Law enforcement will continue to secure the building and initiate all emergency management protocols to release and move students to another location. All other campuses are operating under their regular schedules.”

Authorities responded to shots fired at the school just before 8 a.m. on Friday.

One student told ABC 13 via a telephone interview that she believed the gunman to be a male student, who began shooting in her first-period art class at 7:45 a.m.

The high school’s assistant principal confirmed the shooter to be a student, according to KHOU. The station, citing Federal and county officials, reported that multiple students were killed and an officer was wounded.

WKYC reports “at least eight people” as being dead, citing “multiple sources,” and adding that the number of injuries is unknown at this time.

According to the news station, some students also reported seeing the shooter throw explosives into the classroom.

Authorities said a second suspect was also detained, according to WKYC.

The Brazoria County Sheriff’s Office and the Galveston County Sheriff’s office are responding to the tragedy along with Texas DPS Troopers.
