A woman who was caught driving David Letterman's sports car and once broke into his house has been arrested again, this time while wandering in the comedian's foyer, police said.

Margaret Ray, 36, was arrested Friday night and charged with one felony count of trespassing and one misdemeanor count each of possession of marijuana and possession of drug paraphernalia, police said Sunday.She was being held on $5,000 bond and was to be arraigned Monday.

Police Capt. Michael Angelastro said he could not say how she got inside the house. He declined additional comment.

Ray was arrested last May as she was driving Letterman's $80,000 Porsche. She had come under suspicion because she didn't have $3 to pay a toll.

Police said Ray identified herself as Letterman's wife and introduced her 3-year-old son who was in the car as David Letterman Jr.

Letterman refused to press charges.

A few days later, police arrested Ray at Letterman's three-bedroom house in New Canaan, Conn.

She apparently had moved into the house with her son and lived there for a couple of days while the star of NBC-TV's "Late Night With David Letterman" was out of town, police said.

In September, a judge ordered her to give up contact with Letterman except through the mail and to remain at Fairfield Hills Hospital, where she had been undergoing psychiatric treatment.

She also was ordered to return to her hometown of Crawford, Colo., upon release from the hospital.
