No one has been charged with any crime and the investigation is continuing, Langmesser said.
The bomb that rocked a bustling Manhattan neighborhood contained residue of an explosive often used for target practice that can be picked up in many sporting goods stores, a federal law enforcement official said Sunday, as authorities tried to unravel who planted the device and why.
The discovery of Tannerite in materials recovered from the Saturday night explosion may be important as authorities probe whether the blast was connected to an unexploded pressure-cooker device found by state troopers just blocks away, as well as a pipe bomb blast in a New Jersey shore town earlier in the day.
Gov. Andrew Cuomo, touring the site of the blast in Manhattan’s Chelsea neighborhood, known for its vibrant arts scene and large gay community, said there didn’t appear to be any link to international terrorism. He said the second device appeared “similar in design” to the first, but did not provide details.
