NORWALK — The former operations manager of a Norwalk pediatric practice was charged with larceny and multiple counts of credit card fraud and identity theft after an audit showed a $15,000 discrepancy in the books, police said.

Alexandra DiCamillo, 42, of Heritage Hill Road, New Canaan, was arrested on a warrant Monday and charged with second-degree larceny, and 36 counts each of illegal use of a credit card and identity theft.

According to police, on Feb. 1, officers were called to Advanced Pediatric Center on Cross Street on a report that an ex-employee had made fraudulent credit card purchases.

Police say that the practice’s initial suspicions about DiCamillo were confirmed by an internal audit that reportedly showed $15,390 in credit card purchases and missing funds between September 2017 and January 2018.

DiCamillo had a position of responsibility as operations manager and her duties involved making deposits and withdrawals, bookkeeping duties, payroll, along with having access to multiple business credit cards, according to police.

DiCamillo was hired by the practice in the summer of 2017.

Detectives investigated the complaint against DiCamillo and said that she used her work email to set up personal shopping accounts at Amazon, Peapod, Wayfair, D.H. Gate and others, police said.

According to police, one of the purchases included a dining room set and the credit cards had also been used at Verizon Wireless and a Courtyard by Marriott Hotel in Rhode Island.

Some of the items purchased were reportedly delivered to the woman’s home and others were delivered to the office, according to police.

Police say the practice’s audit also determined that DiCamillo had taken $1,200 in petty cash and paid herself an additional $1,330.

An arrest warrant was obtained and on Monday DiCamillo turned herself in at Norwalk police headquarters.

Her bond was set at $50,000 and she was given a court date of March 19.
