A former adjunct professor at New York City's Columbia Business School who defrauded investors in his company of more than $3 million has been sentenced to two years in prison.
Gregory Rorke was sentenced Friday at federal court in Manhattan. He pleaded guilty a year ago to securities fraud and wire fraud charges. The 63-year-old instructor was arrested in 2014.
Prosecutors say he made false representations to at least 30 investors beginning in 2009. They say his investors included a former student.
Rorke carried out the fraud while he led a Manhattan-based software company he founded, prosecutors said.
U.S. Attorney Preet Bharara said the former professor learned an important lesson in business ethics at his sentencing.
Columbia Business School hasn't responded to a request for comment.
