New Details Emerge About Greenwich Village Couple Arrested On Weapons Charges

NEW YORK (CBSNewYork) -- New details have emerged in the case of a couple arrested over the weekend after police said they found weapons and bomb-making materials inside their Greenwich Village apartment.

When Morgan Gliedman and her boyfriend Aaron Greene were arrested on Saturday, police found a container of the powerful explosive HMTD in their living room, CBS 2 reported. Three buildings in Greenwich Village were evacuated as a result.

HMTD was believed to have been used during the 2005 London bombings.

"It's extremely potent," said Mitch Silber the Executive Managing Director K2 Intelligence. "One of the reasons why it is so appealing for terrorists to use, because they can get all the ingredients for this at local hardware stores."

Gliedman, 27, is the daughter of a prominent real estate agent and a top-rated New York oncologist, CBS 2 reported. She was nine months pregnant at the time of her arrest and gave birth to a baby girl soon afterward.

CBS News has learned that police seized two shotguns, a flare launcher, nine high-capacity rifle magazines, various handwritten notebooks containing formulas, literature on how to make booby traps and homemade weapons, and pages from a do-it-yourself manual called "The Terrorist Encyclopedia."

The New York Post reported Greene was a member of the Occupy Wall Street movement, but the group has denied this.

"The assumption is that the vast majority of people there were peaceful protesters but there was a more radical fringe element to the group and there was a concern that at some point they might turn to violence," Silber said.

Gliedman and Greene have been charged with weapons possession.

Gliedman, who couldn't be arraigned this week while she was in labor, is scheduled to appear in court next week. Greene is being held without bail and is due back in court on Friday.
