A love-struck construction worker who became enthralled with a woman while toiling at her Upper West Side building took his obsession to new heights - rappelling off the roof to the woman's 10th-story apartment and into her bathroom to woo her, authorities said.

Flavio Quito, 29, was working for a subcontractor at the 10-story West 76th Street building between February and May when he "confessed his love and affection" for the 36-year-old resident, according to a complaint filed in Manhattan Criminal Court.

While the woman rebuffed his advances and pleaded with him to stop pestering her, the unrepentant Romeo refused to listen and continued to contact her by phone and mail, the complaint states. Unabashed, he allegedly kept showering the woman with gushy cards, cuddly teddy bears, flowers and other gifts.

But the final straw for his uninterested love interest came on the evening of May 15, when she discovered that her bathroom window was broken - and that someone had been inside her apartment, court papers show.

Earlier in the day, she told authorities, she remembered seeing Quito in the lobby of the building, the records say.
