PHOENIX (Reuters) - The holder of a winning lottery ticket bought in Arizona has come forward to claim half of the record $587.5 million Powerball lottery jackpot, the Arizona lottery said on Friday.

The unidentified ticket holder shares the huge prize in the November 29 draw with a Missouri couple, Mark and Cindy Hill, who claimed their prize a week ago.

The Arizona winner has opted to take $192 million before taxes, rather than the annuity option, the lottery said.
