"The suspect has been taken into custody without incident," the Arlington Police Department said in a tweet. "Most students have been safely evacuated from Timberview High School."

A 15-year-old boy is listed under critical condition and is undergoing surgery. A teenage girl has been released after suffering a minor head injury. 

A 25-year-old man is in good condition in the hospital and a pregnant woman was treated at the school after not being taken to the hospital. Police believe that two of the victims were shot. 

Police found a .45 caliber on the streets near Grand Prairie that is believed to possibly be the gun used in the shooting.

A high school shooting occurred at Timberview High School in the Dallas suburb of Arlington on Wednesday,  and four people have been reported injured. Shots were reportedly fired following a fight. 

In a press conference Wednesday, Assistant Chief of Arlington Police Kevin Kolbye revealed that three of the injured parties had been taken to the hospital and one refused treatment. 

An 18-year-old student, Timothy George Simpkins, was named as a person of interest and is the suspected shooter. He fled the school right after the shooting and is currently being searched for by police. He could be driving a 2018 silver Dodge Charger with a Texas license plate number PFY-6260, according to NBC DFW 5, a local affiliate news station. 

“This is not a random act of violence... this is a student that got into a fight and drew a weapon,” Kolbye said. 

Police were called to the school around 9:15 am right after the fight broke out and shots were reported. 

Kolbye says that Simpkins is “currently at large,” and multiple neighboring police stations and Dallas ATF agents have responded and are on a manhunt for him.
