Diana Duenas-Brown, a former branch manager of Wells Fargo & Co., is suing the company, alleging she was harassed by superiors after alerting company executives regarding improper sales activities, as fallout from its illegal accounts scandal continues, The (San Jose, Calif.) Mercury News reported Dec. 28.

Duenas-Brown reported at least 25 instances of illegal sales activity in 2014 by employees in the Sonoma County town of Windsor where she worked as a branch manager, according to the Dec. 9 federal lawsuit. "Because Duenas-Brown's complaints jeopardized these profits and growth, her supervisors began to retaliate against her for reporting this illegal conduct, discriminated against her, and subjected her to a hostile work environment," the suit stated.

The former branch manager was dismissed in March 2015.
