Brooklyn, NY – The father of terror suspect Najibullah Zazi is now accused of helping to destroy chemicals that were linked to the ongoing terror investigation.

Zazi’s father, Mohammed Wali Zazi, was re-arrested on the new charges unsealed Monday in federal court in Brooklyn, officials said.

The indictment alleges that Mohammed Zazi conspired with others to “corruptly alter, destroy, mutilate and conceal objects” to impede the terror investigation.  Among the items allegedly destroyed, glasses, masks, liquid chemicals and containers.

Zazi’s father was initially arrested on charges of lying to the FBI about his alleged efforts to alert his son about the terror investigation. Najibullah Zazi is charged with plotting to bomb New York City subways.  The younger Zazi, a Queens native who had moved to Denver, is accused of buying hair products and other chemicals in an attempt to build the device.

Zazi is also accused of traveling overseas to Pakistan to meet with al Qaeda operatives for explosives training.  Zazi’s father is expected to be arraigned in federal court in Denver late Monday.   He then would be expected sent to New York for trial.

Last month, two associates of Najibullah Zazi were arrested in connection with the terror investigation.  Adis Medunjanin was arrested on charges he traveled to Pakistan for terror training.  Zarein Ahmedzay is also accused of traveling to Pakistan and then lying to the FBI about the reason for his trip there.

Lawyers for the suspects have denied their clients are tied to terror.
