A video of a D.C. police officer slamming a man into a gate circulated widely on social media Friday, prompting outrage and questions from residents and local officials.

In the video, initially posted to Instagram by murder_mayhem_dc and reportedly taken on Thursday night, a police officer can be seen holding a man’s shoulder and then slamming him over a metal gate. The officer then forces him to the ground to handcuff him. A second man appears to try to push through the group of officers, and police appear to punch and kick him. Someone in the video can be heard screaming in pain, while others yelled “they just broke that man’s back!”

Both men were hospitalized for injuries following the incident. On Thursday, community leaders identified the men injured by police as 23-year-old Ty’Jon Jackson and 30-year-old Tejuan Coleman.

At a press conference Friday, Ward 8 Councilmember Trayon White said he went to the scene of the incident on Thursday night after receiving several messages and calls about a “melee” between the community and police in the 3400 block of Stanton Road.

“This incident was totally unacceptable on so many levels,” White said. “You can clearly see aggressive use of police force in the video.”

In a statement, MPD said that its investigation of the incident is ongoing. Police responded to the area after officers heard the sound of gunshots, according to the department’s account. On the scene, they found an unoccupied, running vehicle with a “visible shell casing” inside of it.

“At that time, a group of subjects approached the officers while they were searching the vehicle,” wrote an MPD spokesperson. “A male in the group threatened ‘to smack’ a female police officer. In response, an officer pushed the male against a fence and took him into custody. Preliminary additional review of [body camera] footage shows that while the man was being taken into custody, another subject began assaulting and strangling officers. The subject was taken to the ground and taken into custody.”

White said that Jackson, who was slammed against the gate, did not suffer a broken back, contrary to social media reports that initially said he did. But, White said, he was treated by paramedics and taken to a local hospital.

Coleman, a second man in the video, was arrested, taken to the Seventh District police station, and later taken to a hospital for medical attention as well.

Aminah Saladin, Coleman’s mother, said at the press conference Friday that her son was maced by police and his hand was injured.

She said she was “horrified” by what she saw in the video.

“I couldn’t believe what I saw,” said Saladin. “Who will protect and serve our community? Instead of being able to sit with the police, we began to be afraid of the police. Who do we call? Do we call 911 before we call Trayon [White] or any other community members?”

D.C. police chief Robert Contee and Mayor Muriel Bowser both said on Friday that the department was investigating the incident and would be reviewing body worn camera footage from the responding officers.

In cases of serious use of force, MPD is required to release body camera footage within five business days, unless the victim’s family objects.

In an interview with Fox 5 on Friday, Contee said that MPD’s Internal Affairs Division was investigating the police response. He said it was too early to determine whether any of the involved officers should be put on leave or have any change in their employment status.

Bowser said Friday that looking at the body camera footage would provide a fuller picture than what the public saw on social media. And she added that while police were still investigating the use of force, she also wanted to focus on the reason why they were on Stanton Road in the first place.

“We can look back and … probably look at more footage than what was put out and see if our personnel acted appropriately,” she said. “What I know, however, is why they were there. They were there because they were investigating a shooting, and we also need to get to the bottom of that.”

Nee Nee Taylor, the executive director of Harriet’s Wildest Dreams, said at a press conference Friday that the shooting in the area did not justify the use of force by police.

“I’m not against trying to prevent crime and stop crime,” Taylor said. “I’m against police violence and brutality. Two things can be true: it could have been a [shell casing] in that car, but that doesn’t give you the right to assault and violently attack Black people.”
