A Zion, Illinois teen known was slapped with felony charges after allegedly saying he’d ’cause a mass homicide’ at his high school should George Zimmerman be acquitted.

One Chicago-area 15-year-old wrote on Twitter Friday: “If Zimmerman free imam shoot everybody in Zion causing a mass homicide, and ill get away wit it just like Zimmerman (sic)” read the tweet from @Mark12394995.

The News Sun-Times reports that the tweet from the Zion-Benton Township High School sophomore was later deleted, but not before several people reported the student to the FBI.

Deputy Chief Steve Dumyahn told the paper that there was no credibility to the teen’s threat.

“He has no weapons and no access to weapons,” he told The Sun Times, adding that the teen was brought into the station for questioning. He was later charged with disorderly conduct.
