AP source: More arrests in inside trade crackdown

A person familiar with the investigation says four more people have been arrested in a wide-ranging Wall Street insider trading probe.

The arrests all occurred outside New York. They're being formally announced later Thursday in Manhattan.

The person spoke to The Associated Press on condition of anonymity because the arrests were not yet public.

The charges came several weeks after a New Jersey consulting firm executive became the first to be arrested in the investigation.

The new federal insider trading probe targets industry analysts, experts and consultants.
