NEW YORK — U.S. authorities on Thursday charged a New Jersey man with conspiring to support the militant group Islamic State, the fourth person arrested in recent days in and around New York City as part of a broader investigation.
Samuel Rahamin Topaz, 21, of Fort Lee, New Jersey, was arrested at his home Wednesday, the Justice Department said. A magistrate judge ordered him detained following a court appearance in federal court in Newark.
According to a criminal complaint, he had communicated frequently with Munther Omar Saleh, a college student from Queens who was arrested Saturday along with an unnamed co-conspirator when they ran at a surveillance vehicle.
Saleh, 20, was accused of plotting to set off an explosive device in the city on behalf of Islamic State.
A third man, Fareed Mumuni, 21, was arrested Wednesday when he tried to stab an FBI agent executing a search warrant at his home in the New York City borough of Staten Island.
The arrests are among a slew of U.S. prosecutions in recent months involving individuals accused of trying to aid Islamic State. Federal officials have said they are actively investigating such cases in all 50 states.
Topaz planned to travel abroad to fight alongside Islamic State, prosecutors said. According to the complaint, an unidentified person who knew him expressed concerns to the FBI that Topaz might travel overseas and “do something stupid.”
The person took Topaz’s passport away at one point, the complaint said.
Saleh, whom the person described as the group’s “leader,” met with Topaz in New Jersey and in lower Manhattan, near the World Trade Center, according to court papers.
On Monday, two days after Saleh’s arrest, Topaz wrote to an unnamed individual, “We gotta leave ASAP,” after he could not reach Saleh, the documents said.
Ian Hirsch, Topaz’s court-appointed lawyer, declined to comment on the allegations, saying he needed time to examine them more thoroughly.
It is not clear whether more arrests are expected. The complaint against Topaz refers to two additional unnamed co-conspirators from New Jersey, including one who left the U.S. in May, allegedly to join Islamic State.
“Providing fighters and resources to a terrorist organization like [the Islamic State] is a threat to our country and its citizens,” New Jersey U.S. Attorney Paul Fishman said in a statement.
