A 21-year-old charged with killing his father with a weed trimmer now faces charges of aggravated battery after authorities say he bit and punched a prison guard Sunday night.

Yashesh Desai, of 3 Plover Court, appeared in DuPage County court Friday.

Prosecutors say Desai resisted leaving his "feces-smeared cell" when it needed to be cleaned, punching and scratching a sheriff's sergeant, as well as biting the officer's finger hard enough to break it, according to the Chicago Sun-Times.
