GRAND PRAIRIE, Texas — Early Friday morning, Arlington Sgt. Michael Chitty was on his way to work. 

"I did not know it was going to turn into all of this," he said.

He was heading westbound on I-30 when the driver of a Lincoln Aviator crashed into a Chevrolet Express van. The van overturned.

Chitty ran over to the accident and got the driver of the Lincoln to sit down. He then went to the van and noticed four people were breaking their way out of the windows. Chitty saw flames on the engine.

He said one man was seriously injured and couldn't move far. 

"I put my arms under his armpits and carried him further away to help get him away from the van, which was engulfed in a matter of moments," Chitty said.

Chitty noticed the driver of the other car started to run away, but he made a choice to help the victims. He gave dispatch details of the suspect.

Chitty already called for fire and rescue. But within moments, another off-duty officer from the Irving Police Department was driving home from work and stopped to help. The Irving officer, who has not been named, assisted with Spanish translation for the victims.

Grand Prairie police officers arrived soon after and blocked off traffic. From the body camera video, the van was clearly covered in flames.

The victims were taken to the hospital. Three were treated and released. One is still being cared for but is listed in stable condition.

Grand Prairie then received a 911 call from the Trinity River Authority, who noticed a suspicious man.

Officer Jason Sloan with Grand Prairie Police Department responded to the call and arrested Jesus Guiterrez. 

"We believe this was the guy who was driving the car and caused the wreck," Sloan said. 

He said 23-year-old Gutierrez was being charged with hit-and-run, failure to stop and render aid, public intoxication and possession of drug paraphernalia. 

Whether on or off duty, the police officers from different departments came together to protect and serve.
