SAN FRANCISCO (KCBS) — A friend of 24-year-old naked acrobat Yeiner Perez Garizabalo described him as “very depressed” as he sits in jail after pleading not guilty earlier this week to two felony and four misdemeanor charges.

His legal troubles stem from his bizarre behavior last month that was caught on tape at San Franicsco’s 16th Street Bay Area Rapid Transit Station.
