Broward Sheriff's Office deputies arrested a 76-year-old man Thursday who they say was going door-to-door in a Lauderdale Lakes neighborhood offering free breast exams. Two women accepted the exams, BSO officials said. At about 9 a.m., BSO investigators say, Philip Winikoff drove to an apartment complex near the 3200 block of Northwest 40th Street. Carrying a black ''doctor's'' bag, he walked up to the building and told a 36-year-old woman that he was in the neighborhood offering free breast exams.
