A federal judge Tuesday increased the prison sentence of a man convicted of planning to join ISIS and to attack an FBI agent. US District Judge Margo Brodie had originally sentenced Fareed Mumuni to 17 years in prison. Following a decision from the US Court of Appeals for the Second Circuit which called the sentence “shockingly low,” Judge Brodie increased the sentence to 25 years.

Mumuni was first taken into custody during a 2015 FBI search of his Staten Island, New York residence. He had pledged allegiance to ISIS and planned to travel to ISIS-controlled territories or to fight in the US. When FBI agents entered his residence, Mumuni attacked one of the agents with a knife. Mumuni pled guilty in February 2017 to charges of conspiring and attempting to provide material support to designated terrorist group ISIS, assaulting and conspiring to assault federal officers and attempted murder of federal officers.

Brodie oversaw Mumuni’s criminal sentencing. Mumuni was sentenced to 17 years in prison—a sharp departure from the 85-year recommended sentence under the United States Sentencing Guidelines. As a result, federal prosecutors appealed the sentence. The Second Circuit agreed with prosecutors that Brodie erred in imposing such a low sentence and remanded case back to Brodie for an increased sentence.
