His threats against police were limited to 140 characters, but a South St. Paul man's Twitter posts have him spending at least 72 hours in jail.
Harrison William Rund, 20, was charged Thursday with felony terroristic threats for several specific Tweets aimed at St. Paul police officers and the state trooper who gave him a speeding ticket on Feb. 4.
Rund was pulled over at 1:29 a.m. in St. Paul and said he first tweeted about the speeding ticket around 3 a.m. St. Paul police learned of the tweets by 11 a.m. that morning and visited Rund's house at 6:30 p.m. that night.
Rund was being held Thursday at the Ramsey County jail. He will be transferred to the Dakota County jail and make his first court appearance Friday or Monday.
"Threats to harm police or law enforcement officials are always taken seriously and will not be tolerated," Dakota County Attorney James Backstrom said. "By this charge we are alleging that these threatening comments were made in reckless disregard of the risk of causing fear to law enforcement officers and the community."
According to the charges, police were also concerned with a photo on Rund's Facebook page of a gun in his waistband. Rund told investigators it was a cap gun that looks like a single-action pistol.
Dakota County Attorney Jim Backstrom told Fox 9 News this case marks the first time he has charged someone for threatening to kill a police officer over social media.
"We take all these threats seriously," he said. "When you threaten the lives of police officers, it's something we are not going to tolerate."
Rund's criminal record includes underage drinking and brawling/fighting charges in the past two years.
