The man seems in the footage to be suffering from some kind of medical episode.The man falls to the ground, where the officer proceeds lean on his back with his knees. The officer appears to deploy the stun gun on him again, this time while he’s already face down on the ground. At this point, other officers join the initial officer in pushing the man into the ground, where they force handcuffs onto him.At one point, the victim yells: “I can’t breathe.”The county’s Chief of Police, Colonel Edwin C. Roessler Jr., says the man “is alive and resting at home with his family.”Roessler also says Timberlake, an eight-year veteran of the department, has been relieved of duty. Other officers who were present have also been relieved of duty pending the result of both criminal and administrative investigations.Timberlake faces up to 36 months of incarceration.2:57 a.m.: St. Louis-area officer suspended after video shows him hitting man with unmarked patrol carAn officer was suspended and two others were placed on leave after a Ring video camera caught an officer driving into a man and then struggling with him on the ground multiple times.Florissant Police Chief Timothy Fagan said the incident happened on June 2 but he only learned about it and saw the video on Saturday. The chief said the FBI and the St. Louis County Police Department are investigating the incident.“My gut reaction was I talked to three different agencies to take a look at it because I do have some concerns about it,” Fagan said.The man seen hit in the video was approached because he was in a vehicle matching the description of another car in connection with shots fired outside the Ferguson Police Department.Police said no weapons were found on the man and he is facing pending charges for carrying drugs and resisting arrest.The man suffered an ankle injury.“I’ll tell you what I believe I see in the video which is that the male then gets up and tries to run and then officer tries to take the male into custody and from my view looks like he struck the individual at least two times, he looks like he kicks him and then hits him with a forearm,” Fagan said.The incident happened on June 2 around 11:30 p.m. in the 9800 block of Eastdell Drive in the City of Dellwood.St. Louis County Prosecutor Wesley Bell will not be looking into the case as his spokesperson’s son, an officer, was in the backseat of the car the detective was driving when he hit the man, creating a conflict of interest for Bell.The case was turned over to St. Charles County Prosecuting Attorney Tim Lomar as a result.Fagan said there is no body or dash camera footage to review.The officer that was suspended had been with the department for nine years.12:42 a.m.: Several officers injured due to improvised explosives in SeattleThe Seattle Police Department confirmed that several of their officers were injured after people at a demonstration began throwing rocks and bottles at officers and by setting off improvised explosives.The incident occurred at approximately 7:30 p.m. according to the Seattle Police Department, when demonstrators outside the East Precinct began moving barricades without permission and the police asked them multiple times to stop.The condition of the officers is not currently known.11:14 p.m.: Minneapolis mayor booed after saying he does not support abolishing policeMinneapolis Mayor Jacob Frey was booed out of a protest after he said he did not support abolishing the police department.A protester asked Frey if he supported defunding the police department, however, he did not answer that question and instead said he “did not support the full abolition of the police.”Boos quickly permeated through the crowd and protesters chanted, “Go home Jacob! Go home!”Activists have called for defunding police departments in the U.S., often meaning taking money out of the police budget and putting it toward the community. Los Angeles Mayor Eric Garcetti announced such a measure earlier this week.ABC News’ Courtney Pomeroy, Alexis Zotos, Abigail Shalawylo, Ahmad Hemingway and Alexandra Faul contributed to this report.
