RadarOnline.com has also learned that the alleged extortionist lived with one of the women whom David was once involved with.  RadarOnline.com has learned that woman's name is Stephanie Birkitt.

Birkitt still works on Letterman's show, but is no longer involved with the talk show host.

The affair happened a long time ago, before his son Harry was born, and before he got married, but he was living with his wife to be at the time.

Police say Halderman needed money and decided to target Letterman.

The scandal became public Thursday when Letterman told his audience  that he received a package from someone three weeks ago claiming to have evidence of improper relations between him and Late Show employees and threatened to reveal them to the public unless he paid $2 million.

The extortionist was given a phony $2 million check and his arrest followed that transaction.

A source close to the situation told RadarOnline.com that Letterman met with Halderman several times as part of the police operation leading to the arrest.

Speaking on his show Thursday night, at one point, Letterman said: "This morning, I did something I've never done in my life. I had to go downtown and testify before a grand jury."

WNYW-TV in New York  has obtained the search warrant in the extortion plot that led to a sting and two meetings between Halderman and investigators.

According to the warrant, Letterman was identified as "Client 1."

• In the package he received, Halderman allegedly includes treatment for a screen play with supporting materials.

• The supporting materials had copies of parts of a diary and personal correspondence belonging to Halderman's girlfriend, Stephanie Burkett, a former assistant to Letterman.

• A reference is made to "Client 1's great personal success and his beautiful and loving son."

• Halderman allegedly says he was publishing a book that had a lot more documents that would be incrementing including photos, letters and emails.
