A homeless man accused of stalking tennis star Anna Kournikova (search) pleaded innocent Tuesday to battery and other charges stemming from his arrest on her neighbor's pool patio.

William Lepeska (search), 40, has been jailed in a psychiatric unit on $250,000 bond. He could face 30 years in state prison if convicted of two counts of battery on police officers, resisting arrest and burglary, all felonies. He also faces misdemeanor charges of stalking, indecent exposure and criminal mischief.

Circuit Judge Diane Ward (search) set a trial date for May 2 for Lepeska, who sat in court with his ar of swimming nude across Biscayne Bay, bound for Kournikova's $5 million Sunset Island estate Jan. 30. He was arrested when he turned up at the wrong house and started yelling, "Anna! Save me!"

Lepeska, who has the name Anna tattooed on his right arm, has served a prison term in Wisconsin for stabbing a man sleeping in a university student union coffeehouse. In the Milwaukee case, he cited Old Testament sacrifice and told police that he needed to sacrifice his victim "to appease the power of evil."
