The plot unraveled when the NYPD’s Intelligence Division began conducting surveillance earlier this year on a group of Muslim men in Brooklyn.
One of the men arrested yesterday had been thrown out of the group, sources said.
“Whether this is al Qaeda or an unstable lone wolf doesn’t make much of a difference as to the danger,” said a law enforcement official.
The men, described as being in their 20s, don’t appear to be connected with Osama bin Laden’s al Qaeda network, sources said.
During the course of the investigation of the Brooklyn group, cops learned the two men had mentioned they wanted to bomb a train and went so far as to draw up sketches of the station, sources said.
