Erik Williams, 21, of the 3600 block of South Michigan Avenue, was arrested in Chicago on May 18 and charged with sexually assaulting (forced fellatio) a 42-year-old woman.

The victim arrived at a police station in the early morning hours clutching, in her hand, testicles that she had just bitten off.

At about the same time, Williams showed up at Michael Reese Hospital missing his testicles.

Doctors confirmed that the testicles were Williams but were unable to reattach them.
