LOS ANGELES  — Two people charged with trying to extort millions of dollars from pop star Stevie Wonder pleaded no contest on Monday and were released after being sentenced to time-served in jail.

Alpha Lorenzo Walker and Tamara Diaz were sentenced to serve 292 days in jail and three years of probation for attempting to sell a video that purportedly portrayed Wonder in a negative light. Jail credits made the pair eligible for release Monday.

The pair was arrested in May after the Grammy-winner’s attorney arranged a sting and claimed Walker had sought up to $5 million for the video.

Walker’s attorney, Ian Wallach, said the deal was reached after prosecutors encountered trouble proving the extortion case and that the charges were eligible to be reduced to misdemeanors and expunged later if the pair comply with the terms of their release.
