The father of Najibulla Zazi, the alleged terrorist bomber with ties to Al Qaeda, has been charged with obstruction of justice by federal prosecutors in Brooklyn today. The father, Mohammed Wali Zazi, 55, was first arrested in September along with his son, Najibullah Zazi, 24. The younger Zazi has been charged with conspiracy to use a weapon of mass destruction, and will be on trial in Brooklyn starting in February. Both father and son were initially indicted in Denver on less serious charges, but were moved to Brooklyn when the NYC terror plot (using beauty products) came to light.

According to City Room, Zazi was accused in the indictment of attempting to “corruptly alter, destroy, mutilate, mutilate and conceal objects, to wit: glasses, masks, liquid chemicals and containers, with the intent to impair the objects’ integrity and availability” for use in a grand jury proceeding.

Earlier this month, feds also arrested several friends and associates of the Zazi's. According to City Room, Brooklyn federal prosecutors say they expect to file additional charges against the younger Zazi, and two other men implicated in the plot, which U.S. Attorney General Eric Holder once called, "one of the most serious terrorist threats to our country since Sept. 11, 2001."
