Rep. Gary Condit "broke off his close friendship" with missing intern Chandra Levy only two days before she disappeared, the congressman told investigators, according to Fox News Channel police sources.

Condit, D-Calif., provided the new details about his relationship with Levy in a second, hour-long interview with police Saturday, but stopped short of saying whether he and the 24-year-old had a romantic relationship, the sources said. Condit did, however, strongly hint that the two had been lovers, the sources said.

When Condit delicately broke things off with Levy with the explanation that she was moving back to California, she was distraught, refusing to take no for an answer and even becoming obsessed with him, the sources said.

Levy called Condit several times on a special line in the 24 hours before she vanished, but he never returned those calls, the sources said.

Condit, 53 and married, has repeatedly said through public statements that he and Levy were only good friends, with his staff denying there was a romantic relationship.

Condit's chief of staff, Mike Lynch, said Thursday that Condit didn't even remotely discuss a relationship or breaking one off one during the police interview.

Lynch also reiterated Thursday that Condit had nothing to do with Levy's disappearance.

Levy's parents, Susan and Robert Levy of Modesto, Calif., have hired former Washington homicide detectives to scour their daughter's Washington studio apartment for fibers, love letters, notes and any other clues that could help them find out what happened to their daughter, who has not been seen since April 30.

In another development, a 39-year-old flight attendant told the FBI she ended a year-long romantic relationship with Condit when she saw press reports about the missing Washington intern, a source close to the woman told Fox News.

Ann Marie Smith said she has not spoken to Condit since one or two weeks before the 24-year-old disappeared. Smith also said she knew the California Democrat was married and suspected he might be seeing someone else, but she didn't know for sure.

Smith also said Condit told her he was "lonely in Washington," with his chronically ill wife spending 99 percent of her time in California. 

Smith said she had no information on the Levy case.
