BELFAST, Maine — A former employee of a popular Belfast eatery has been accused of embezzling about $15,000 during a five-month span, according to police.

Sarah Fuller, 30, of Belfast had been employed by Bell The Cat, whose owners had at first noticed the change in their expected profits just after they had moved the business to a different location, according to Detective Sgt. Bryan Cunningham of the Belfast Police Department.

“Initially, they thought they just weren’t doing as well at the new location,” he said Friday.

But the owners eventually figured out that they were being robbed, according to Cunningham. They let Fuller go in January 2013, and police have been putting together the investigation for more than a year. She was charged earlier this month with Class B theft, according to police records.

Cunningham said that Fuller, a longtime employee, is accused of voiding transactions and taking more money than was shown in the original transaction. He said he investigated alleged thefts from August 2012 to January 2013.

Fuller was arrested on April 1, and taken to Waldo County Jail in Belfast to be booked. She was released on $500 cash bail the following day, according to a jail official.
