ROCKAWAY TOWNSHIP, N.J.—Police say there was more on the menu than Munchkins and lattes during the late shift at a Dunkin’ Donuts in northern New Jersey.

A 29-year-old female is facing prostitution charges after police say she took breaks to provide sex in exchange for money.

Rockaway Township police launched an investigation known as “extra sugar” after getting a tip about the workers activities at the shop.

Detective Sgt. Kyle Schwarzmann told The Daily Record of Parsippany ( http://bit.ly/nrX40w ) he noticed that 29-year-old Melissa Redmond of Mine Hill would go out to cars and would spend 10 to 15 minutes in the vehicles.

Schwarzmann says Redmond was arrested after soliciting sex from an undercover officer.

No one at the Dunkin’ Donuts wanted to comment.
