New York (CNN) -- A man from New York plans to plead guilty Tuesday to making false statements in what federal authorities have described as a plot to detonate bombs on New York subways, two sources said.
Ahmad Wais Afzali, Muslim cleric and funeral director from the New York borough of Queens, was among the first people charged in the alleged plot.
He is expected to plead guilty in federal court in Brooklyn, New York, on Tuesday afternoon, the source said. Afzali's defense attorney did not immediately respond to a call from CNN.
Robert Nardoza, a spokesman for the U.S. attorney in Brooklyn, declined to comment.
Afzali is charged in a four-count indictment. He's accused of lying about whether he tipped off Najibullah Zazi that the FBI had been asking questions. Zazi subsequently pleaded guilty to conspiring to detonate explosives in the United States.
Afzali faces a possible prison sentence of up to five years on each count and possible deportation.
Afzali's attorney, Ron Kuby, denied his client tipped off Zazi. He said Afzali knew he was being monitored and that he was trying to help investigators as they asked for information about Zazi.
