The daughter of a prominent New York doctor and her Occupy Wall Street-organizer boyfriend were arrested after police discovered an explosive used for making bombs and a cache of weapons in their upscale New York City apartment, it was claimed.

Morgan Gliedman, 27, and Aaron Greene, 31, were taken away from their home in Manhattan's pricey Greenwich Village on Saturday. 

Gliedman, who is nine months pregnant, remains in jail, where she is likely to stay until at least New Year's Day, the Manhattan District Attorney's Office told MailOnline. 

She is the daughter of a top Brooklyn cancer doctor and was educated at the Dalton School, an exclusive New York prep school attended by the likes of Anderson Cooper and Claire Danes. 

Greene, the father of the child, went to Harvard University for his undergraduate degree and did graduate work at the Kennedy School of Government there, as well. 

He was being held without bond.

The New York Post reports that police found seven grams of HMTD, a high explosive powder that was reportedly used in the 2005 London Underground bombings.
