Morgan Gliedman, 27, and Aaron Greene, 31, were arrested Saturday in their Manhattan apartment after officers with a search warrant found 7 grams of HMTD, a highly explosive white powder used in bomb making. Police also seized a flare launcher, a sawed-off shotgun, nine rifle magazines and various how-to manuals on building bombs and booby traps.
“They had a terrorist encyclopedia, they had improvised and modified firearms, deadly homemade weapons, a do it yourself machine gun…” New York City Police Commissioner Raymond Kelly said Monday.
Kelly was unsure how much damage 7 grams of HMTD would cause.
HMTD is homemade explosive similar to TATP, the latter made with hydrogen peroxide and other fairly easily available ingredients. TATP caused a furor in homeland security for a few years even though no terrorists were successful with it in the US. (The Zazi case being the big example.)
The police had the apartment building evacuated. Seven grams of HMTD is not a threat to such a structure.
The preliminary report asserts the couple were heroin users.
