( CNN ) -- The 24-year-old man accused of attacking commuters while naked at a San Francisco subway station proclaimed he is not guilty Tuesday . According to the San Francisco District Attorney 's office , Yeiner Garizabalo waived his arraignment and entered not guilty pleas . He is due back in court on July 18 for a pre-hearing conference . The native of Colombia remains in jail on a $ 100,000 bond and a request from U.S. Immigration and Customs Enforcement officials . Garizabalo faces seven charges following the May 10 incident at a Bay Area Rapid Transit station . He appeared in a bizarre video where he , sans clothing , performed acrobatics off subway equipment , then went after commuters trying to catch a train . A video of the incident quickly went viral . In it , a glistening man with a wild mane of hair turns fare gates into balance beams , doing splits and back flips buck-naked . Startled commuters flee as he dashes across the station , attacking people at random . Last week , police said he had been arrested , given a mental evaluation , charged with battery and released . He now stands accused of two felony counts of false imprisonment , four misdemeanor counts of battery and one misdemeanor count of sexual battery in the incident , said Alex Bastian , a spokesman for the District Attorney 's office . California defines false imprisonment as `` the unlawful violation of the personal liberty of another . '' Garizabalo , who is also known as Yeiner Perez , was , until recently , a member of the ClownSnotBombs Circus . The group posted a statement on its Facebook page Monday saying he was no longer affiliated with it . `` To our knowledge , Mr. Perez never exhibited this type of behavior previously and this episode came as a complete surprise to us , '' it said . On Tuesday , the group added another statement that said it had worked with Garizabalo to have him admitted to a hospital for a psychiatric and medical examination . That was supposed to happen Tuesday , but he was arrested on Monday . The post , signed by six members of the troupe , said Garizabalo described to them being in a play at the train station on May 10 . `` Now that he has seen the video and understands the gravity of what really happened , he feels both guilty and horrible for what he has done , '' it said . `` He is extremely depressed , under a lot of stress and very afraid . '' CNN affiliate KTVU reported Garizabalo faces deportation because of an expired visa .
