(Bloomberg) U.S. prosecutors are preparing to file charges this fall against traders from several banks involved in a bid-rigging scheme to manipulate Libor rates, not just Barclays Plc (BARC), according to a person familiar with the case.

The charges against individuals, which would probably be filed by October according to the person, center on alleged rate-fixing activity that goes beyond the conduct described in last month’s settlement between Barclays and regulators in the U.S. and U.K.

Initially prosecutors were aiming for as soon as Labor Day, the U.S. holiday on Sept. 3, to charge traders who illegally manipulated Libor rates.
