The NYPD wants to question three people who were involved in a clash between a right-wing group and leftist protesters on the streets of the Upper East Side on Friday night, officials said.

Police released a tweet with photos of the three men, who were involved in a fight between members of the right-wing group the “Proud Boys” and protesters who were demonstrating against the group’s leader speaking at a Republican club on the Upper East Side.

“We continue to investigate the violent incident on the UES on Friday night, and need information regarding these persons-of-interest,” the NYPD wrote in the tweet.

The Proud Boys’ leader, Vice Media co-founder and right-wing provocateur Gavin McInnes, delivered a speech at the Metropolitan Republican Club Friday evening.

The club was vandalized prior to McInnes’s appearance, and scuffles between members of the Proud Boys and protesters broke out after his talk.

Three protesters were arrested for assault after the fight, but the NYPD is hoping to speak with the men pictured in their tweet for additional information, a spokeswoman said.
