VIDEO-ISIS Using Social Media to Recruit 'Lone Wolf' Bombers, Authorities Warn | Fox News Insider

Rick Leventhal reported this morning (video above) from Times Square on new concerns that ISIS is trying to inspire "lone wolf" bombings on high-profile targets like the heart of Manhattan or the Las Vegas strip.

New York City Police Commissioner Bill Bratton calls it a "new era of potential terrorism," but said right now there are "no credible, specific threats to the city."

Leventhal pointed to an online chat room, claiming to be affiliated with ISIS, that provided information on making pipe bombs out of household materials like matches, sugar and Christmas lights.

The new post suggests locations and advice on covering one's tracks and doing maximum damage. Leventhal said the concern is that someone not connected to ISIS will attempt an attack on their own.

The report comes on the heels of the arrest of a man in upstate New York for allegedly trying to recruit ISIS fighters.

More on the arrest from

Mufid Elfgeeh, 30, of Rochester, was indicted by a federal grand jury on three counts of attempting to provide material support and resources to the group widely known as ISIS that has been designated by the U.S. as a foreign terrorist organization, federal prosecutors said Tuesday. Elfgeeh, who was born in Yemen and is a naturalized U.S. citizen, is one of the first people accused by the U.S. of recruiting on behalf of ISIS. 

According to court documents seen by the Rochester Democrat & Chronicle, Elfgeeh tried to raise money to enable a Yemeni man to join ISIS. At one point, Elfgeeh allegedly sent the man $600 to travel from Yemen to Syria. An FBI affidavit alleges that this past April, Elfgeeh traveled to Buffalo with an FBI informant to get a passport for the latter man. Elfgeeh suggested that ISIS would use the informant to "operate a cannon, act as a sniper and/or build bombs," the document claims. 

Elfgeeh was arrested this past May in the parking lot of a local Wal-Mart after taking delivery of two handguns equipped with silencers and ammunition. Elfgeeh had allegedly given the informant $1,050 in cash to purchase the handguns, which had been rendered inoperable. Federal authorities said he bought the weapons as part of a plan to kill members of the U.S. armed forces returning from war, as well as Shiites in the Rochester area.

Prosecutors said two of the three individuals Elfgeeh had contact with were cooperating with the FBI. 

"Disrupting and holding accountable those who seek to provide material support to foreign terrorist organizations is and shall remain a critical national security priority," said Assistant Attorney General for National Security John Carlin.

The investigation included linking Elfgeeh's home computer to tweets from alias Twitter accounts expressing support for Al Qaeda, violent holy war and Sunni insurgent groups in Syria, according to court papers.

One message allegedly from Elfgeeh read, "al-Qaida [sic] said it loud and clear; we are fighting the American invasion and their hegemony over the earth and the people."

Elfgeeh is also charged with one count of attempting to kill "officers and employees of the United States," two counts or possession of an unregistered firearm silencer, and a count of possession of firearms and silencers in furtherance of a violent crime. He is scheduled to appear in court for arraignment Thursday. 

Elfgeeh's lawyer, Assistant Federal Public Defender Mark Hosken, told the Democrat & Chronicle that he would enter a not guilty plea in response to all the charges.
