A federal grand jury has charged the father of an airport driver accused in a terror plot with conspiring to obstruct a criminal investigation of the matter.

A newly unsealed indictment says Mohammed Wali Zazi conspired to destroy and concealed chemicals, glasses and masks in the criminal probe of Najibullah Zazi, who was charged in September with plotting to attack New York City with homemade bombs.

Najibullah Zazi has pleaded not guilty to charges of conspiring to use weapons of mass destruction. He is being held without bail in New York.

Mohammed Zazi also pleaded not guilty. He has been free on bail and is being monitored electronically.

Mohammed lives in Colorado. He has a court appearance set for Monday afternoon in Denver. A New York court date hasn't been set.
