NEW YORK (AP) _ The founder of the Guardian Angels remained in critical but stable condition Saturday with bullet wounds from an ambush as he got into a cab.

Curtis Sliwa, who's in Bellevue Hospital's intensive care unit, was visited by his wife, Lisa, added Veronica Brundage, a hospital spokeswoman.

Sliwa, 38, was ambushed Friday when he got into a cab near the headquarters of his civilian crime-fighting group. About six hours after Friday's shooting, police found the taxi less than a mile from the shooting, but investigators had no suspects.

Sliwa's surgeon, Dr. Leon Pachter, said Sliwa will stay in the hospital up to two weeks. He already has undergone five hours of surgery and might need more in two to three months.

''I doubt there will be any lingering effects,'' Pachter said.

The surgeon said Sliwa was wounded in both legs, the bladder, colon and rectum. Pachter wouldn't say how many times Sliwa was hit, but said one bullet remained in his body.
