NORWICH – Acting on information provided by security officials at NBT Bank, police arrested a former teller Friday for allegedly stealing tens of thousands of dollars and falsifying company records to cover it up.

According to the felony complaint submitted to Norwich City Court Monday, 26-year-old Kimberly N. Aitken of Doing Road, Norwich, allegedly stole $77,797.50 over a period of time between February 2008 and March 2009.

During that time, Aitken worked for NBT as a teller supervisor at the company’s main branch on South Broad Street in Norwich.

“The bank’s robust security and investigative department notified the Norwich Police Department on Thursday, April 16 that they had uncovered a situation with one of the bank’s employees. They provided documentation that greatly assisted the Norwich PD and the Chenango County District Attorney’s Office with filing the appropriate charges,” said Norwich Police Chief Joseph Angelino.
