In June 2001, an anonymous two-page handwritten letter was received from an individual ostensibly living in Lackawanna who knew the immigrant Yemeni population intimately. It warned, "I am very concern. I am an Arab-American... and I cannot give you my name because I fear for my life. Two terrorist came to Lackawanna... for recruiting the Yemenite youth... the terrorist group... left to Afghanistan to meet... bin Laden and stay in his camp for training", and gave the names of twelve local youths.
