TORONTO -- A 70-year-old man is facing charges after police say numerous residents of an affluent Toronto neighbourhood were defrauded of more than $600,000.

Police allege that between February 2012 and August of this year, a man frequented the Yorkville area and portrayed himself as a prominent businessman and investment broker.

Police say the man convinced his victims to invest in his company, or allow him to invest on their behalf, and numerous victims were defrauded of about $605,000.

The man is alleged to be the sole owner of the companies, which did not have any other employees.

Albert Allan Rosenberg of Toronto faces four counts of fraud over $5,000.

Police say there may be more victims and anyone with information is asked to contact investigators.
