NEW YORK (CNN) - A Muslim cleric and funeral director from New York has been indicted on charges that he lied to federal agents about a Colorado man who has been charged with plotting a terrorist attack in the city.

Ahmad Wais Afzali, 37, was indicted late Monday on four counts of making false statements to federal agents, according to the U.S. District Court for the Eastern District of New York.

Afzali's attorney, Ron Kuby, confirmed the indictment, but said he had not yet received a formal copy.

Afzali was charged in September with lying to the FBI in its investigation of Najibullah Zazi, who has since been charged with plotting a terrorist attack. Afzali pleaded not guilty at that time.

Afzali, who is from the New York borough of Queens, was released a few days after his arrest on $1.5 million bail. He is allowed to travel to work and the mosque for worship, and is under electronic monitoring.

Zazi, 24, and his father, Mohammed Wali Zazi, were arrested in September by federal agents in Denver, Colorado. The elder Zazi also was charged with making false statements to investigators.

Najibullah Zazi was indicted 10 days later by a federal grand jury in New York on one count of conspiracy to use weapons of mass destruction - bombs - against unspecified targets in the the United States.

The Zazis have pleaded not guilty.

Investigators have said that the younger Zazi plotted to make bombs from household chemicals, and planned to be in New York "with the intent of using" a bomb on September 11.

In the indictment against Zazi, investigators said he purchased large quantities of beauty supply products and had notes on his laptop computer that included formulas for making triacetone triperoxide, or TATP, a highly volatile, highly explosive compound.

TATP can be made from widely available chemicals, including hydrogen peroxide; acetone, the main ingredient in nail polish remover; and muriatic acid, a diluted form of hydrochloric acid.

Zazi arrived in New York from Denver on September 10, but became suspicious that he was being tracked by law enforcement, authorities said. He bought an airline ticket and returned to Colorado on September 12.

If convicted, he could face life in prison.
