Bergen County Prosecutor John Molinelli says investigators also found several assault rifles and other weapons when they searched Rivera's home Friday night. Ridgewood police had initially responded to the home after receiving a report that potentially hazardous materials might be at the residence.

The FBI and Bergen County Bomb Squad investigated, according to the Bergen County Record.

Prosecutors said Rivera is unemployed but has a license to practice medicine in New York.

According to a source familiar the case, Rivera told a girlfriend that he was going to build a bomb. She then alerted police. Rivera had not chosen a target.

The source said that some anarchist literature was found in Rivera's home.
