"Diff'rent Strokes" actress Dana Plato refused a couple's offer to bail her out of jail after her arrest for investigation of armed robbery, Las Vegas authorities said Sunday.

The former child star from the TV sitcom turned down the offer Saturday by Tony and Beverly DeMarco, who put up the $1,300 in cash. Plato, 26, rejected the offer because she didn't know the couple, said her attorney, Paul Fitzgerald."She was all upset," Fitzgerald said. "Her concern now is that not knowing these people who are doing this type of thing, what are their motives? She's a wreck."

Plato was arrested Thursday after a clerk in a video store identified her as a woman who took $164 at gunpoint, police said. Police said they later found a pellet gun resembling a 9mm pistol in Plato's apartment behind the store.
