A northern New Jersey physician has been indicted on charges he caused the risk of widespread damage by stashing large amounts of bomb-making materials at his home.

Sixty-year-old Roberto Rivera of Ridgewood also faces weapons charges in the indictment recently handed up by a Bergen County grand jury. He remains jailed on $1 million bail. His lawyer has declined to comment.

Rivera was arrested in November after authorities reported finding several weapons at his home, along with large amounts of chemicals that can be used in making explosives. Police went to the residence after receiving a report that potentially hazardous materials might be there.

Prosecutors haven't said why Rivera had the items or what he planned to do with them.

The state temporarily suspended his medical license in January.
