NEW YORK, Nov 5 (Reuters) - Fourteen people were charged with fraud and conspiracy in a dramatic widening of an insider trading scandal that has ensnared hedge fund managers, top Silicon Valley executives and a bevy of white-shoe advisers.

In complaints that read like scripts for the TV series "The Sopranos," prosecutors alleged suspects dropped off bags full of cash, used prepaid cellphones to dodge wiretaps, and used nicknames such as "the Greek."

"As we allege, some of the defendants -- taking a page from the drug dealer's playbook -- deliberately used anonymous, hard-to-trace, prepaid cellphones in order to avoid detection by law enforcement," federal prosecutor Preet Bharara told a news conference.
