(CNN) -- After a six-week operation dubbed "Extra Sugar," police determined that a New Jersey donut shop employee was offering more than coffee and sweets to her customers and arrested her on a prostitution-related charge, police said Tuesday.
Melissa Redmond, an overnight worker at a Dunkin' Donuts shop on U.S. Route 46 in Rockaway, was arrested because she was offering sexual services for money, according to Detective Sgt. Kyle Schwarzmann of the Rockaway Borough Police Department.
The original anonymous tip came in early June and police started surveillance on Redmond, 29, soon after, according to Schwarzmann.
The major break in the investigation occurred after an undercover officer, or "John" went to the shop and spoke with Redmond, Schwarzmann said. The officer reported that during their initial meeting he was offered sexual services for money, he said.
The undercover officer met Redmond again around 3 a.m. on July 27 and was given a list of prices for what she had to offer, Schwarzmann said. Redmond took the money she was offered and was arrested, he said.
She was "forthcoming about everything," according to Schwarzmann.
Police said they discovered that Redmond had been offering her services on and off for the past three years.
Redmond, who faces a prostitution-related disorderly person charge, was released on her own recognizance and is scheduled to appear in court on August 10.
Attempts to reach Redmond or find if she is represented by an attorney were not immediately successful.
The franchise owner of the Dunkin' Donuts shop put Redmond on unpaid administrative leave pending the outcome of the investigation, according to Dunkin' Brands Inc., spokesman Andrew Mastrangelo.
