Wells Fargo's annual shareholders' meeting turned rowdy Tuesday as at least four audience members loudly protested the company's sales practices, one of whom interrupted a nun.

Despite the tumult, shareholders re-elected all 12 board members.

Earlier in the day, one shareholder demanded that board members explain what they knew about the bank's fake account scandal and when they knew it.

Another ripped into the board for not taking action sooner as its employees created more than 2 million accounts for customers without their knowledge. More than 5,000 employees were fired including several top executives who were forced to give back salary.

"You did it that way and you allowed it to continue for years!" one man shouted.

Three protesting shareholders were removed by security.

Another speaker, Sister Nora Nash, director of corporate responsibility for the Sisters of St. Francis of Philadelphia, also was critical of the board. She said the board "failed to set the tone and the culture" that it should have. She was interrupted briefly by one of the protesters.
