According to federal authorities and a revised indictment, a New York City man is accused of planning one of the most devious terror plots since Sept. 11.

Najibullah Zazi, Adis Medunjanin and Zarein Ahmedzay were accused of allegedly planning to bomb Manhattan subways. They were arrested in 2009 before their plan went underway. However, a new indictment revealed a fourth man is accused of meeting with Medunjanin to travel to Pakistan in order to take part in the Jihad, according to NY1. Little is known about this man and he is refered to only as John Doe.

A lawyer for Medunjanin wanted the government to reveal the identity of the man before his trial in March. The U.S. attorney's office in Brooklyn has not released a comment.
