LOS ANGELES - A man known for brokering deals involving compromising celebrity photos and videos has agreed to plead guilty in a plot to extort more than US$1 million from Tom Cruise for the actor's stolen wedding photos, court documents unsealed Thursday showed.

David Hans Schmidt, 47, has agreed to plead guilty to one count of sending communications for purposes of extortion. He faces up to two years in federal prison and a $250,000 fine under a plea agreement filed Aug. 24.

It wasn't known when Schmidt, who is free on $100,000 bail, might enter his plea in court. A phone message left for his lawyer, Nancy Kardon, was not immediately returned Thursday.

Meanwhile, a plea agreement for Schmidt's co-defendant was filed under seal Aug. 24, a federal court docket in Los Angeles showed. Marc Lewis Gittleman, who authorities say helped recover photos from a computer hard drive, has been charged with conspiracy to commit extortion.

Gittleman, 33, faces up to five years in prison. His lawyer, Michael Nasatir, declined comment because the plea agreement is under seal.

Gittleman and Schmidt were arrested July 26 after U.S. authorities said Gittleman obtained photos of Cruise's wedding in Italy last year to Katie Holmes from the event's official photographer, court documents show.

Gittleman then made copies of photos on the drive and kept them for himself, authorities said. He contacted Schmidt after finding a website touting his abilities to broker celebrity photos.

Starting in May, Schmidt had repeated contact with Cruise representatives and threatened to release the photos if he didn't receive between $1.2 million and $1.3 million, officials said.

Authorities said Schmidt sent multiple e-mails to Cruise's camp, including one with 13 wedding photographs attached as proof he had them. Schmidt also said there were about 7,600 images and he hoped a "commendable and quiet arrangement could be reached" with Tom Cruise, court documents said.

Schmidt attended a Los Angeles meeting with the actor's representatives and an undercover FBI agent July 24 in which he compared his actions to "legal extortion" and said he would "hunt down to hell and back" anyone who crossed him, court documents said.

Schmidt also has tried to auction off Paris Hilton's diaries, along with photos of her in various stages of undress and other personal items that had been locked away in a Los Angeles-area storage locker until a few months ago.

He has claimed to have brokered deals to sell a sex video of Dustin Diamond, who played Screech on "Saved by the Bell" and a video of skater Tonya Harding's wedding night, published reports said. He also claimed to have obtained topless shots of rescued U.S. army prisoner of war Pte. 1st Class Jessica Lynch.

A phone message left with Cruise's publicist was not immediately returned.
