New York City police have released a video of the man who is accused of attacking a group of cops – and the New York Police Department's highest-ranking uniformed member – during a protest on the Brooklyn Bridge.

The NYPD's Crime Stoppers unit shared the video late Wednesday in a tweet that also announced a reward of up to $2,500 for any information that leads to the person’s arrest.

Shortly after 10 a.m. on Wednesday, the man allegedly swung the wooden object at a group of high-ranking NYPD members, including Chief of Department Terence Monahan, while they were making an arrest. The assault was caught on video, which was later posted to the NYPD’s Twitter account.

Police said three officers were seriously hurt, including one who suffered an injury to his eye socket. Monahan suffered an injury that was not life-threatening to his hand.

Thirty-five people from the protest were arrested or ticketed, police said, with 26 receiving summonses, several others were issued desk-appearance tickets and five were fully charged.

When asked about the protest during a Thursday morning protest, New York City Mayor Bill de Blasio said an attack on a police officer is "absolutely unacceptable."

"There's no situation in which it is acceptable to attack a police officer. Period," he said, adding that he spoke to Monahan after learning of the attack. "Here's what is the reality: anyone who does that will suffer the consequences."

He continued: "We've said this now for months, I've said it very clearly: peaceful protest is honored in New York City, always has been. There is no acceptable violent protest. Any violent protest will be stopped and there'll be consequences for anyone involved and anyone."

De Blasio was also asked when he had last spoken to Police Commissioner Dermot Shea, who has been noticeably absent from the mayor's daily press conferences, and said they last talked on Tuesday.
