Mayor Bill de Blasio announced the $15,000 fine on Monday night, weeks after thousands packed into the Yetev Lev temple in South Williamsburg to celebrate the wedding of Yoel Teitelbaum, grandson of Satmar Grand Rabbi Aaron Teitelbaum, on Nov. 8. The identity of the younger Teitelbaum’s wife is unknown publicly. The New York Post obtained video footage from the wedding showing the pews crammed with people without a mask in sight.

“We know there was a wedding,” the mayor told the local news network NY1. “We know it was too big. I don’t have an exact figure, but whatever it was, it was too big. There appeared to be a real effort to conceal it. Which is absolutely unacceptable.”

“We’ve been through so much,” de Blasio added. “And in fact, the Williamsburg community in recent weeks responded very positively, did a lot more testing, and was being very responsible. This was amazingly irresponsible, just unacceptable. So there’s going to be consequences right away for the people who let that happen.”
