A woman angry at workers for being denied free frozen yogurt retaliated with an act of public lewdness in Montclair.

The Montclair Police Department says they responded to 16 Handles after receiving a report from employees on July 21.

The workers said the woman entered the business, obtained a cup of frozen yogurt and stated that she did not have money to pay.

When the employees told her she could not take the yogurt, she became irate, exited the business, approached the front-facing glass window and exposed her buttocks to everyone inside.

Investigators say she then turned around, removed her pants again and exposed her genitals.

No arrests have been made. The suspect was last seen leaving the area wearing black sunglasses and carrying two red bags.
