NEW YORK (AP) A Florida stockbroker has pleaded guilty in a case in which he and others were accused of cheating clients out of millions of dollars by misrepresenting the prices at which securities were bought and sold.

Marek Leszczynski of Miami entered the plea Tuesday to conspiracy to commit securities fraud and wire fraud. Two others already have pleaded guilty in the case and are awaiting sentencing.

Authorities say the 44-year-old stockbroker worked at the New York offices of a London-based firm, Linkbrokers Derivatives Corp., when the scheme was carried out from 2005 until December 2008. Prosecutors say Leszczynski and the others carried out the scheme to increase the company's profits and secure a large bonus.

Sentencing is scheduled for Dec. 19. Leszczynski faces a maximum of five years in prison.
