Barclays bank has been accused of misleading large institutional investors by duping them into buying protection measures from predatory high-frequency traders, New York's attorney general said.
The allegations against the British banking and financial services firm were contained in a securities fraud lawsuit that Eric Schneiderman announced at a Manhattan news conference.
The NY attorney general accused the bank of "a flagrant pattern of fraud, deception and dishonesty with Barclays clients and the investing public," in a complaint filed in the Supreme Court.
