An 18-year-old student is in police custody after four people were seriously injured in a shooting at Timberview High School in Arlington, Texas.
On Wednesday morning, a fight is believed to have broken out in a classroom before the student began to open fire, CNN reports.
The 18-year-old suspect, an 18-year-old man named Timothy Simpkins fled the scene in a vehicle, according to authorities. When he was located by police, he was charged with three counts of aggravated assault with a deadly weapon.
As reported by ABC News, there were four victims altogether - three of whom were students, and one who is thought to be a teacher.
Three out of the four victims were taken to hospital including a 15-year-old boy who had gunshot wounds and was in a critical condition, a 25-year-old man who suffered gunshot wounds but was in a good condition, and a teenage girl with abrasions who has now been discharged.
A family member has named English teacher Calvin Pettitt as one of the victims.
Simpkins spoke to a lawyer before turning himself in without incident just before 1:15 PM. According to law enforcement, he has been booked into the Arlington City Jail. His bond has been set at $75,000.
Police have stated that the incident was not a random act of violence and alleged that Simpkins had been involved in a fight before the shooting, which occurred at about 9:15 AM in a classroom on the second floor of the building.
In an interview with ABC News, a teacher revealed that when he heard the sound of gunshots, he barricaded himself with his students inside a classroom.
Texas Governor Greg Abbott has since released a statement about the ordeal:
"Our hearts go out to the victims of this senseless act of violence. Thank you to the law enforcement officers and first responders who arrived on the scene to help the victims and prevent further violence.
"I have spoken with the Mayor of Arlington and offered any assistance the state can provide, and I have directed the Texas Department of Public Safety to make state resources available to help bring the criminal to justice."
