MINNEAPOLIS — A Minneapolis man who’s charged with tweeting threats against FBI agents and a judge will remain jailed without bail pending further proceedings.

U.S. Magistrate Judge Franklin Noel ruled at a hearing Monday that the government had met its burden of proof for keeping 19-year-old Khaalid Adam Abdulkadir in custody, but he said it was a close call.

Abdulkadir is charged with one count of impeding and retaliating against a federal law enforcement officer. Authorities said he posted threatening tweets after the Dec. 9 arrest of his friend, Abdirizak Mohamed Warsame, on one count of conspiring to provide material support to the Islamic State group.

Defense attorneys said the government has yet to prove that Abdulkadir posted the tweets.

Relatives testified that Adulkadir is not religious and doesn’t support the group.
