Gov. Andrew Cuomo joined a press conference in upstate Kingston on Friday to announce the arrest of a man accused of locking a female co-worker in a refrigerated cooler and yelling, “You’re in the gas chamber, you f–king Jew.”

“It’s hard for me even to believe this is happening,” Cuomo said of the incident on March 11 at the Mother Earth’s Storehouse.

William Sullivan, 21, of Saugerties, NY, was arrested for the hate crime. He has no previous criminal record.

Sullivan allegedly turned off the lights in a small refrigerated cooler with the co-worker inside before uttering the hateful comments.

The victim is reported to be unharmed and is “handling it as well as expected.”

The store where she worked has come under attack for not firing Sullivan immediately after the victim’s mother filed a complaint.

But after Sullivan was given a second chance, he allegedly harassed the victim again and was finally axed.

The store later issued an apology.

Cuomo said the incident was not an isolated case against Jews.

“We have been seeing a growing number of anti-Semitic activity,” he said.

He said in New York alone, between 2016 and 2017, there was a 90 percent increase in anti-Semitic attacks.

He also highlighted a January 2019 incident in which three Hasidic Jewish men were viciously attacked in Brooklyn.

Sullivan was charged with aggravated harassment in the second degree.

He is scheduled to appear in court next week.
