Investigators believe they know possible accomplices of Afghan immigrant Najibullah Zazi, who is accused of plotting a terrorist attack against New York City, according to an Associated Press report, which cites a law enforcement source.
A federal indictment mentions at least three people helping Zazi buy peroxide and acetone in suburban Denver from beauty supply stores. According to security experts, those chemicals can be used to make explosives.
Federal agents and NYPD detectives working the case know the identities of three New Yorkers they believe are involved in some way, the AP reports.
Authorities arrested Zazi and his father in Denver last week. His father was released on bail. Zazi was transported to New York to face a federal judge in connection with an alleged plot to set off explosives on commuter trains to coincide with the Sept. 11 anniversary.
He has denied any involvement in terrorism.
The Joint Terrorism Task Force also arrested an imam from Queens for allegedly lying to investigators.
Last Thursday, a federal magistrate freed Ahmad Afzali on $1.5 million bail.
"This is my land, this is my country, I love this place," Afzali said Thursday after his release. He has been an NYPD informant.
"Zazi used to come to the mosque, then he would disappear from the mosque and the last time I saw him was many years ago," he said.
