Robert Wilson, aged 34, was the manager at the town’s Church Street branch of Nationwide Building Society, having worked his way up after starting as a customer representative in 2015.
Shrewsbury Crown Court heard in Thursday that Wilson of Ffordd Pentre, Mold, Clwyd began stealing the building society’s money over a 42-month period from September 2019 until April 2023.
The court heard that he stole £34,020.85 from his own till, and adjusted receipts on the accounting systems known as the SAMM and BOSSS Journal viewers to cover his tracks and also allow him to steal a further £7,090.
Wilson, who appeared before Judge John Butterfield KC on Thursday for a sentencing hearing, had previously admitted one count of theft and one count of false accounting at a magistrates court hearing in July.
