A Manhattan Supreme Court judge was duped into sending $1 million to a Chinese bank in an email scam, sources said.

Justice Lori Sattler, 60, opened an email earlier this month that appeared to be from her real estate lawyer and told her to wire the large amount of cash overseas, according to law enforcement sources.

Sattler, who had believed she was purchasing a piece of property, confirmed the transfer when her bank contacted her to question to $1 million figure, the sources said.

The NYPD and the FBI are investigating the incident.
