A tipster just emailed us to say that his girlfriend Stephanie was walking around Sue Bierman Park in San Francisco's Financial District today and happened across a creepy-masked busker who looked strangely familiar.

The naked man who was filmed running wild through San Francisco's 16th Street BART Station last month was identified late yesterday as 24-year-old Yeiner Garizabalo, a former circus acrobat who apparently suffered a nervous breakdown.
