Terror suspect David Coleman Headley pleaded not guilty on Wednesday, to helping plan the deadly 2008 Mumbai attacks and plotting to attack a Danish newspaper which published cartoons of the Prophet Mohammed.
Headley, 49, appeared in court in an orange jumpsuit, shackled at the ankle, accused of being a scout for two different Pakistani-based terrorist groups who used a friend's Chicago-based immigration company as a cover for his surveillance activities in India and Denmark.
Headley is accused of making trips to Mumbai over a period of almost two years, even taking boat tours around the city's harbor to scope out landing sites for the attackers, who killed 166 people including six Americans.
He changed his name from Daood Gilani in 2006 so he could "present himself in India as an American who was neither Muslim nor Pakistani," charging documents said.
He was arrested in October over a plot to attack a Danish newspaper that printed incendiary pictures of the Prophet Mohammed, but on Monday US justice officials released a raft of new charges related to the Mumbai attacks.
