Watch this. Within seconds, THEY START THROWING PUNCHES. THIS IS CELL PHONE VIDEO OF two NYPD narcotics detectives wrangling with an unnamed man in Brooklyn. >> They say he was resisting, but look closely. What exactly is he doing here? This happened in Brooklyn during a narcotics operation. Police say they were looking for a suspect, but they grabbed the wrong man. His name is Timothy Brown. According to police, he matched a general description, including clothing. Officers moved in quickly, took him to the ground, and began striking him multiple times. Surveillance video shows him being dragged across the store floor, even over broken glass. Police later said Brown was resisting arrest. But a former NYPD lieutenant reviewed the video and said the level of force appears excessive, especially since Brown never attacked the officers. The guy, I can hear him say, "Wait, what's going on?" The officers did not say, "We're NYPD." They didn't say that we're detectives. They didn't tell him, "You're under arrest. Put your hands behind your back." They just started UH HITTING HIM. ABAALE MORAN CAN BE OVERHEARD ON THE video yelling at officers as the man crashes into a shelf stacked with wine bottles. The officers continue to throw punches, at one point kicks the man >> cut with those glass bottles. They dragged him in glass. They dragged him in the glass. It happened Tuesday afternoon around 4:00 p.m. at this liquor store near the intersection of Baltic and Hoyt Streets in Cobble Hill, Brooklyn. I'm so mad at myself that I didn't throw my body against him to protect this man, you know? The NYPD says the two undercover detectives had just witnessed a narcotics purchase, and the man in the turquoise hat and shorts fit the description of a suspect. >> I feel like everybody saw police beating a man like it was a video from the 1950s and the 1960s. In 2026, these police officers are supposed to be under control. >> WE ARE CALLING ON DISTRICT ATTORNEY Eric Gonzalez TO FILE CHARGES THE SAME WAY HE WOULD this black man on THE CORNER OR THAT SPANISH MAN ON THE CORNER. MAYOR Murmdani addressing the incident posting, "The violence used by NYPD officers in this video is extremely disturbing and unacceptable. Officers should never treat a person this way. The NYPD is conducting a full investigation into this incident." This matter is under internal review by our Internal Affairs Bureau, and we'll have more to say about it as that investigation unfolds, but I understand the community interest in it because it is an upsetting video. But this is where everything changes. The charges against Brown dropped. Police confirmed he was not the suspect they were looking for. A Brooklyn man bloodied and beaten after a violent arrest by two NYPD detectives that was caught on camera. And tonight, police admit they arrested the wrong man. Only hour Masa Saidi sat down with him and his family, who said he feared for his life. >> Praying none of this ever happens to anyone else. And um I want justice. Timothy Brown tells me he was attacked without explanation while buying wine after work. He's a security guard and home health aide. What did they say? He said, "You're under arrest." I remember being grabbed and shoved, and he said, "Don't resist." And I said, "I'm not resisting." They slammed me up against the the um the glass. You know, repeatedly hitting me in the temple and my head. You know, you see my eye black. I just thank God that I'm alive. That's all I can say. And it didn't stop there. Multiple officers, including supervisors, were placed on modified duty. Now, the entire narcotics unit is under a 90-day review. The NYPD says a 90-day review of its narcotics section has been underway. The department increasing its oversight and reviewing the training detectives receive. And here's the part raising even more questions. Officers were supposed to have body cameras on. They didn't. It's like another stab in the heart. Gwen Carr's son, Eric Garner, died in 2014 after an officer placed him in a banned chokehold. Carr says the commissioner has promised to enforce existing body camera policies. There's a lot of um promises that she made, so we just have to hold her feet to the fire and see that this all comes to pass. And now, another man says he was also wrongfully detained in the same operation. As outrage grows over Timothy Brown's arrest, tonight new video is raising more questions about what else may have happened during that same drug operation. It shows a second man in handcuffs near Hoyt and Baltic last Tuesday. I don't get in trouble, so you know It was really it was really embarrassing. Last week, Ronald Maxwell told me he too was taken into custody during that same drug operation. He claimed he was taken to the 84th Precinct and released without charges. At the time, the NYPD said, "Quote, there is not an arrest on file based on the information provided." Today, we sent the NYPD this surveillance video obtained from the store. An employee tells us it was recorded during that same drug sweep, where the NYPD says detectives were looking for a drug dealer's associate dressed in green. Maxwell says, like Brown, he was wrongfully taken into custody. And the man in the surveillance video is him. The department says its response is the same. Quote, "There's not an arrest on file based on the information provided." So, it's likely not just Brown and Maxwell. We have obtained video that appears to show two others placed in handcuffs on that day. We've asked the NYPD if these men were in fact taken into custody and why. So far, the NYPD has declined to answer that question. Police experts tell me you can take people into custody if you have reasonable suspicion that they've committed a crime. KJ, the question is is wearing green enough to meet that bar? We don't know. Community activists are now demanding criminal charges against the officers involved, and the NYPD commissioner has stepped in directly. Tonight, NYPD's Internal Affairs Bureau is investigating. Police Commissioner Jessica Tisch says the officers have been placed on modified duty with their guns and shields removed. >> We'll have more to say about it as that investigation unfolds, but I understand the community interest in it because it is an upsetting video. How did this happen? The NYPD says police were looking for a drug dealer's associate wearing green shorts. They spotted someone nearby who matched that description and tried to arrest him. Brown was initially charged with resisting arrest and obstruction, but now all charges have been dropped. His mom, Donna Brown, tells me the video left her outraged. >> And I was like, "You know what? I'm going back to the precinct to make sure he's going to be okay. Excuse me. Cuz I felt like the police was going to beat him up some more. >> It's disgusting. It really is. It's disgusting. And they do it all the time to our black and brown people, all the time. And lots of reaction tonight. Mayor Murmdani calls the video unacceptable. He says officers should never treat a person this way. Meantime, the union for NYPD detectives says police put their lives on the line every single day. They say if you don't comply during an arrest, what do you think is going to happen? But KJ, what happened is what is under investigation. >> Well, even the commissioner there admitting that the video is hard to watch. >> So, the question becomes, if police arrest the wrong person, use force, and then charge them anyway, what happens next? The police union says that if you don't comply, what do you think is going to happen? But they didn't need compliance. They needed the right person. Because when the system gets it wrong, compliance doesn't protect you. Thin blue lives, baby.
