Rajaratnam’s Wiretapped Call With Brother Bolsters Insider Case

A wiretapped telephone call between Galleon Group LLC’s Raj Rajaratnam and his brother Rengan was used by prosecutors to bolster their case against the hedge fund co-founder in the insider-trading trial.

Yesterday, Rajiv Goel, who had worked in Intel Corp.’s treasury group, returned to the witness stand to testify that he leaked secret information to his friend Raj Rajaratnam. His testimony centered on his alleged 2008 tip that Intel would invest $1 billion in a new wireless network company formed by Clearwire Corp. and Sprint Nextel Corp. Prosecutors played several recordings of Goel telling Rajaratnam about the deal.
