MINNEAPOLIS — A Minneapolis man accused of threatening FBI agents and a judge over Twitter after his friend was arrested for allegedly conspiring to help the Islamic State group will have his case go before a federal grand jury for review, a judge ruled Wednesday.

Khaalid Adam Abdulkadir, 19, is charged with one count of impeding and retaliating against a federal law enforcement officer. During a preliminary hearing, U.S. Magistrate Judge Franklin Noel found there was probable cause to believe a crime was committed and he allowed the case to proceed. Abdulkadir will remain in custody pending a Monday detention hearing.

Authorities say Abdulkadir posted the threatening tweets last week after his friend, Abdirizak Mohamed Warsame, was arrested on one count of conspiring to provide material support to the Islamic State group. According to court documents, within hours of Warsame’s arrest, Abdulkadir posted two tweets that contained threats. One included the words “kill them FBI.” The other included, “I’m kill them FEDS for take my brothers.”
