According to TMZ, Nazario's dog was in the backseat and suffered from the pepper spray.
During the arrest, the suit says Nazario had his hands up, offered no resistance, but was pepper sprayed and violently knocked to the ground and detained.
Lt Nazario, who is Black and Latino, was in uniform and driving with a temporary paper licence plate on his back window on 5 December, when he was told to pull over in the town of Windsor. When Nazario didn't immediately pull over, Crocker said the driver was "eluding police" and considered it a "high-risk traffic stop".
The traffic stop was captured on Nazario's cellphone video, and the body-worn cameras worn by Crocker and Gutierrez, according to the lawsuit. "Yeah you should be", an officer says.
In body camera and cell phone video, Army Second Lieutenant Caron Nazario, still in his uniform, can be seen with his hands visible out of the window of his new vehicle. Both of the officers involved have their guns drawn on him.
Nazario claims he was simply trying to find a well-lit area to stop in since it was nighttime.
Attorney Jonathan Arthur, who is representing Lt Nazario in the lawsuit, said that the army officer knew it was vital he kept his hands on show.
When a police cruiser signaled for him to stop, the lawsuit says Nazario put on his blinkers, slowed down and looked for a lighted place to stop. Nazario has his hands up during the whole encounter.
Mr Nazario also accused the officers of threatening to destroy his military career by charging him with multiple crimes if he complained about their conduct. The US Army officer had been pepper-sprayed and in agony. Nazario can be heard repeatedly asking the officers "What's going on?", to which officer Gutierrez replies, "What's going on?"
"This is a colloquial expression for an execution, originating from glib reference to execution by the electric chair", the lawsuit states.
The officer then opens the door and repeatedly demands he get out of the vehicle. Gutierrez responded with "knee-strikes" to his legs, knocking him to the ground, the lawsuit says.
The lawsuit states: "These cameras captured footage of behaviour consistent with a disgusting nationwide trend of law enforcement officers, who, believing they can operate with complete impunity, engage in unprofessional, discourteous, racially biased, unsafe and sometimes deadly abuses of authority". "He's an officer in the United States armed forces", Arthur said.
Both traffic police officers remain on duty and no disciplinary action has been taken.
