(Reuters) - A grand jury indicted a New York man arrested on Saturday after police found an explosive compound, bomb-making manuals and weapons in a Greenwich Village apartment he shares with his girlfriend.
Aaron Greene, 31, appeared briefly in a New York courtroom on Friday, and was informed of the indictment by a judge. He was returned to jail without bail.
Formal charges against Greene were set to be announced at a January 29 court appearance, when he is expected to enter a plea, prosecutors said.
Greene's girlfriend, Morgan Gliedman, who was nine months pregnant when she was arrested, gave birth over the weekend to a baby girl and remained hospitalized in police custody, a law enforcement source said. It was unclear when she would be formally arraigned.
