Wells Fargo recently discovered that some workers altered documents about business customers, raising new concerns about the embattled bank’s internal system of checks-and-balances.

The improper activity took place in 2017 and early 2018 and was brought to light by multiple Wells Fargo (WFC) employees who alerted management, a person familiar with the matter told CNNMoney.

The document altering happened in Wells Fargo’s business banking group, which caters to medium-sized businesses with annual sales of $5 million to $20 million.
