OKLAHOMA CITY — An Oklahoma police officer is under investigation after newly released body-worn camera footage shows him throwing a 70-year-old man to the ground during a dispute over a traffic ticket.

The The Oklahoma City Police Department said Lich Vu was hospitalized after the October 27 incident for “serious injuries.” Thuan Nguyen, president-elect of the Vietnamese American community in Oklahoma, told USA TODAY on Tuesday that he visited Vu in the hospital last week and that he was on a feeding tube after suffering a brain bleed and a neck injury.

“In our community, we want to make sure we see justice in that these things don’t happen to another person,” Nguyen said.

The police department said it is conducting an internal investigation and Officer Joseph Gibson is on administrative leave. The findings will be presented to the Oklahoma County District Attorney’s office once the survey is complete.

“The Oklahoma City Police Department is committed to transparency and accountability,” the agency said in a statement. “We want our community to know that this case is being thoroughly investigated and that the review process will take time. We ask for your patience as we work to complete this investigation.”

The incident in the Oklahoma state capital drew calls from community leaders for accountability as the nation nears the end of what could be a record year for police killings, according to Mapping Police Violence. Human rights lawyers have documented excessive police force in the nation for years and show the data The US far outstrips other rich countries in law enforcement violence.

The newly released video sheds light on the October 27 incident

The Oklahoma City incident began with a minor one-vehicle collision involving Vu and another driver.

Body-worn video camera released Friday begins with Vu sitting in the driver’s seat of his parked car with the door open while Gibson sits in front of him in a sunny parking lot. The officer said Vu made an improper turn and told him to sign a citation, noting it was not an admission of guilt.

The footage then showed Vu telling the officer he would not sign the ticket. Vu got out of the car and gestured to the road as he appeared to explain the accident. A woman then appeared in the body camera video and stood next to Vu.

Gibson is heard telling Vu he’s going to jail if he doesn’t sign the ticket.

“I’m ready to go to jail,” Vu replied as they sat in the parking lot.

“Are you ready to go to jail?” Gibson said. “Ridiculous. FINE. That also involves impounding your car.”

Gibson pulled over to speak with the other driver involved in the crash and issued him a ticket. When he returned to Vu, they continued to argue about the summons. Vu appeared to hit Gibson’s chest with the back of his hand.

“You shut up,” said Vu.

Gibson quickly grabbed Vu’s arm and twisted him around before throwing him to the pavement as he said, “Get down.”

Vu still appears for the rest of the video. The woman leans into Vu’s face and says, “I need an ambulance.”

Gibson replied, “Yeah, I’ll call an ambulance” as he handcuffed Vu. The footage ends a few seconds later. Police said the handcuffs were removed after paramedics were called.

The Oklahoma City Police Department did not immediately return USA TODAY’s request for comment Tuesday.

Vietnamese American community leaders are demanding justice

While Nguyen said the community faces “implicit bias” in encounters with police, it usually doesn’t escalate to the kind of “violent outcome” that led to Vu’s hospitalization.

Nguyen said he and other Vietnamese American community leaders met with the Oklahoma City police chief on Thursday, and the police department released the body-worn camera footage the next day.

“We want to work with our officials,” Nguyen said.

In addition to potential harm, Nguyen said language barriers can hinder communication with law enforcement. He went on to say the community wants to hold police accountable for the incident, conduct community training on how to interact with law enforcement and make sure people know their rights.

Report: Police use force against 300,000 people a year

Mapping Police Violence Organization appraisal that US law enforcement officers use force on at least 300,000 people each year, and about 30% are injured as a result. The group noted that most of the people officers use force against are charged with non-violent crimes.

The group has been tracking police killings since 2013, and the death toll reached a record high last year, at 1,247 deaths. Most officer-involved crimes began with traffic stops, mental health checks, disturbances, non-violent crimes, or when no crime was charged, according to Mapping Police Violence.

So far this year, the group said law enforcement officials have killed 1,045 people all over the nation.
