"Just two days before the 10th anniversary, New York City is on high alert.
Federal and local authorities have beefed up security after receiving intelligence about a credible threat. The alleged plot by al Qaeda involves detonating car bombs on bridges and in tunnels in New York and Washington D.C. to coincide with the anniversary of 9/11.
Chopper 2 HD got a look at the NYPD in action on Friday — police cruisers and orange cones marked one checkpoint on the George Washington Bridge. On the West Side Highway, at one of the many checkpoints, police were stopping drivers and searching vehicles, specifically vans and trucks. There is also a threat to bridges and tunnels.
Security was equally tight at Penn Station, where armed guards were keeping watch over travelers as Transportation Security Administration agents performed random bag checks, swiping packs for gunpowder.
The crossroads of the world came to a grinding halt at various times Friday because for police Times Square has become the ground zero of the latest terror threat. Sources told CBS 2’s Marcia Kramer that another attempt to explode a bomb there is a key concern, and the intelligence suggests it could be a dirty bomb.
Based on informant information authorities are looking for three suspects. One is believed to be an American citizen. Two others apparently have U.S. travel documents.
Some of the information on the latest threat could be coming from Younis al-Mauritani, the man hand-picked by Osama bin Laden to develop terror targets in the United States. He’s a “most wanted list” senior al Qaeda operative who was arrested in Pakistan last week with his computer, BlackBerry and other tools.
Top security officials told Kramer this is the al Qaeda way. Their 1993 attempt to topple the World Trade Center failed, so they came back again on 9/11. Shahzad’s car bomb fizzled, so now they want to try again.
But that’s only half of the problem. Officials are worried that this time it could be a dirty bomb..." (Source)
