Police Commissioner Dermot Shea says unmasked NYPD officers caught on video forcibly removing a passenger from the subway system after that person asked the officers why they weren't wearing masks will be disciplined.

"There is no excuse for what I saw in that video. We are better than that," Shea said. 

"Nobody is getting fired over this incident, nobody is getting suspended over this incident," Shea added. "But at the same time I am not in any way shape or form attempting to downplay that."

The incident happened Tuesday morning at the 8th Street Station in Manhattan.

The man involved in the encounter with the police, Andrew Gilbert, told NY1 he walked over to the officers, who he says were not wearing masks, and asked them why they weren't following department rules. 

Gilbert said one of the officers was pretending he couldn't hear him, saying, “I can't hear you through your mask.”

Another woman witnessed the incident and started filming.

Gilbert said that's when officers declared he was being disruptive and forcibly removed him from the station.

He says the police officer yelled, “If you're not going to ride the train, then you can leave."

"There's really no accountability there. They can just violently attack people in public for asking them to follow the rules,” Gilbert told NY1. “If you want to be a law enforcement officer, enforce the laws. And if you want to enforce the laws, follow the laws yourself."

Mayor Bill de Blasio on Wednesday called the video "troubling."

"I didn't like what I saw one bit," de Blasio said at a news conference. "I did not see everything except for the clip at the time when the person was being removed, but I saw the officers not wearing their masks in the subway. That's evident that's unacceptable. We've given this instruction a thousand times and if you're going to be in law enforcement you actually have to participate in following the law."
