A second woman has accused heavyweight champion Mike Tyson of grabbing her at a Manhattan disco last weekend.

Loris Davis, 29, of Bay Shore on Long Island, said Thursday that she was dancing at Bentley's Disco Lounge about 2 a.m. Saturday when "someone grabbed my behind under my dress."She said she whirled around and screamed: "Try that again and I'll slap . . . you."

"Then it dawned on me that I was screaming at the heavyweight champion of the world," said Davis, who plans to file a lawsuit against Tyson.

Asked if her dance partner confronted Tyson, she replied: "No, the man had common sense."

Davis said she was going to ignore the incident until she read of a similar accusation made over the weekend by another woman in the same club.
