COLUMBIA, Mo. (AP) – A University of Missouri student who police say was upset over the results of the U.S. presidential election is accused of posting a threat on a social media app.

Columbia police say 23-year-old senior chemistry major Gregory L. Phipps was arrested Wednesday on suspicion of misdemeanor harassment. He later was released on $500 bond.

Police say Phipps was upset early Wednesday about Republican Donald Trump’s victory when he posted under his own name on the app Erodr the message, “Some of you should be ready to die tomorrow.” The message went on to say, “If you want to topple a country, prison is the least I can do to show you what you deserve.”

A message Wednesday by The Associated Press to Phipps’ campus email account was not immediately returned.
