 A Baltimore police officer was suspended with pay by the department Saturday after a viral video emerged showing him repeatedly punching a man in the face before taking him to the ground. UPDATE: Baltimore officer from viral beating video resigns, police confirm » 
 
 Interim Police Commissioner Gary Tuggle said he was “deeply disturbed” by the video, and that the incident is under investigation. “The officer involved has been suspended while we investigate the totality of this incident,” Tuggle said. “Part of our investigation will be reviewing body worn camera footage.” 
 
 Police said a second officer on the scene at the time of the incident was placed on administrative duties pending the outcome of the investigation. In the now-viral footage, the officer and the man, whom his lawyer identified as Dashawn McGrier, can be seen talking to each other. Brown said McGrier was not being charged with a crime, but was taken to a hospital and was having X-rays taken of his jaw, nose and ribs late Saturday for suspected fractures from the altercation. Brown said McGrier had a previous run-in with the same police officer — whom he identified as Officer Arthur Williams — in June that resulted in McGrier being charged with assaulting the officer, disorderly conduct, obstructing and hindering, and resisting arrest. Brown said that in that incident and in the one Saturday, McGrier was targeted without justification by the officer. Tuggle did not identify the officer or the man who was punched, but the department said the officer has been on the force for just over a year. At Williams’ graduation from the police academy last year, he received awards for top performance, including for high marks in "defense tactics, physical training and emergency vehicle operations,” for his "academic achievement, professional attitude, appearance, ability to supervise,” and for his "tireless and unwavering dedication" and "outstanding leadership ability,” according to a video of the graduation ceremony. Smith said officers are required to fill out a contact sheet any time they talk to a citizen in relation to any type of investigation, no matter how brief the encounter. The police department said that one of the officers is familiar with McGrier and that “the situation escalated” after McGrier refused to give officers identification. Brown said that the Saturday encounter was a “follow-up” to the June incident and that the officer cornered McGrier and placed his hands on him “for no justifiable reason.” 
 
 “What went on out there yesterday was not professional; it’s personal,” Brown told The Washington Post on Sunday. Josh Rosenblatt, the academy’s head of legal instruction, told the Baltimore Sun that a third of recruits don’t have an understanding of the laws on constitutional policing, but the department gives them badges anyway. “While I have an expectation that officers are out of their cars, on foot, and engaging citizens, I expect that it will be done professionally and constitutionally,” he said. 'Zero tolerance' for this behavior 
 
 Tuggle said he was appalled by the incident and has "zero tolerance for behavior like I witnessed on the video." Officers have a responsibility and duty to control their emotions in the most stressful of situations.” 
 
 The incident occurred Saturday outside Q’s Bar and Liquors in the 2600 block of E. Monument St. in East Baltimore. The officer starts throwing punches and continues pummeling the man for the next 12 seconds, the bystander's video shows. The officer throws repeated punches, shoves McGrier onto rowhouse steps and continues beating him until McGrier lands on the pavement. A video of the June 26 encounter showed McGrier being held on the ground by the same officer, Brown said. “Don’t touch me,” McGrier told the officer, who then repeatedly punched the man. What led up to the attack 
 
 The incident began around 11:45 a.m. while officers were working on "a crime suppression detail related to crime in the area," Baltimore police spokesman T. J. Smith said. The Baltimore City State’s Attorney’s Office is investigating the incident and has not commented. Mosby’s office did not respond to a request for comment. The police department said Mosby’s office “provided information related to this case,” but did not explain what that meant. Mayor Catherine E. Pugh (D) said she has seen the video and has “demanded answers and accountability.” 
 
 “We are working day and night to bring about a new era of community-based, constitutional policing and will not be deterred by this or any other instance that threatens our efforts to re-establish the trust of all citizens in the Baltimore Police Department,” Pugh said.
– An incident that "deeply disturbed" Baltimore's interim police commissioner has led to one police officer's resignation and another being put on administrative duty. CNN has bystander video of a man shouting at one officer as another stands nearby; the first starts throwing punches and 10 seconds later both men are on the ground, with the officer on top and blood from the civilian streaked across the sidewalk. The second officer is seen trying to get his hands into the tussle but doesn't appear to try to stop the first officer's punches. Neither officer has been identified, but Warren Brown, an attorney repping the civilian, identifies his client to the Baltimore Sun as 26-year-old Dashawn McGrier. Brown says the cops stopped his client without offering a reason; witnesses tell the Sun the officer who threw the punches knew McGrier and may have targeted him. In a statement, the Baltimore PD says the cops stopped McGrier as part of a crime probe; they say McGrier refused to provide ID for a citizen's contact sheet, said to be required when cops talk to a citizen during an investigation. After initially being suspended, the punch-throwing officer resigned, per the Baltimore PD; the second officer is still on administrative duties pending an investigation. McGrier wasn't charged, police say. Brown says McGrier suffered jaw, rib, and nose fractures, per the Washington Post. "I have zero tolerance for behavior like I witnessed on the video today," Gary Tuggle, the PD's interim commissioner, said. "Officers have a responsibility and duty to control their emotions in the most stressful of situations." Brown says McGrier will sue, per WBAL. Baltimore is still haunted by the 2015 death of Freddie Gray.
