WASHINGTON (AP) _ Boris Korczak took pride in his work as a double agent stealing KGB secrets for the CIA. But that work came with a price, he contends in a lawsuit.

Korczak says the CIA owes him $725,000 plus interest for the seven years he spent giving Soviet intelligence to CIA contacts in Copenhagen, Denmark. According to the lawsuit, Korczak reached an agreement with the then-CIA station chief in Denmark to serve as a double agent on the promise that if his cover was blown the CIA would pay resettlement and living costs.

``He was putting his life on the line every day,'' said Korczak's attorney, Randy Mott. ``Any day, any time of the day, if he was compromised, he could have been taken out.''

The CIA, not surprisingly, has very little to say about Korczak's allegations, even after he filed suit Wednesday in the U.S. Court of Federal Claims.

``The agency neither confirms nor denies the existence of a covert intelligence relationship,'' CIA intelligence support division Chief Frederic Manget wrote to Korczak's lawyer on Jan. 23. ``The agency's position is that your client is not entitled to any compensation from the agency, regardless of the existence of such a relationship.''

To date, according to Korczak, the CIA has reimbursed him for some gasoline and meals during his time in Copenhagen. But beyond that, he claims, all he has gotten for his troubles is a couple of attempted assassinations at the hands of the KGB and a mysterious poison pellet shot into his right kidney.

Korczak, 56, a native of Poland, says he served as a double agent in Copenhagen from 1973 to 1980, funneling vital information to the CIA while he fronted as an electronics importer supplying defense technology to the Soviet KGB.

Now a permanent U.S. resident living in Fairfax, Va., on refugee status, Korczak left Copenhagen hastily in 1980 after, he says, a drunken CIA agent blew his cover at an October Revolution party thrown by the Soviet Embassy in Denmark.

In 1980, shortly after arriving in the United States, Korczak said he met in Oakton, Va., with a man he identifies as his CIA contact, William Lofgren. He alleges that Lofgren urged him not to sue the CIA and offered to help in exchange for a bribe of Russian religious icons along with a diamond ring and several gold items totaling $300,000 in value.

There is no telephone listing for a William Lofgren in Oakton. CIA spokesman Mark Mansfield declined to comment on the case.

Korczak told reporters Wednesday that ever since he arrived in the United States he has been trying, without resorting to legal action, to gain the compensation he feels he's due.

Korczak has some official backing for his claim. In 1983, Sen. Charles Grassley, R-Iowa, took up Korczak's cause and wrote officials that he had been informed by ``responsible people in the national security field'' that Korczak had worked for the United States for several years.
