The Consumer Financial Protection Bureau is dropping its lawsuit against the company that runs the Zelle payment platform and three U.S. banks as federal agencies continue to pull back on previous enforcement actions.

It had accused Zelle's operator and owner banks of failing to adequately investigate fraud and refusing to reimburse victims.

The Consumer Financial Protection Bureau dropped its case Tuesday against the peer-to-peer payment network along with Charlotte-based Bank of America and Wells Fargo, which has its largest employment hub in the city. JPMorgan Chase was also named in the lawsuit filed in December.
