The plane, which took off from Chicago O’Hare International Airport bound for Frankfurt, was in the air for about two hours before it landed early due to the incident, according to FlightAware. Usiripalli was taken into custody at Boston Logan International Airport, authorities said.
Usiripalli was charged with one count of assault with a dangerous weapon with the intent to do bodily harm.
He faces up to 10 years in prison, up to three years of supervised release and a maximum fine of US$250,000, according to the US Attorney’s office.
“Usiripalli presently does not have lawful status in the US,” the US Attorney’s office said, adding that he had previously been admitted to the country on a student visa and was recently enrolled in a master’s programme for biblical studies.

The Federal Aviation Administration has warned that airlines have seen “rapid growth” in unruly passenger incidents in recent years.
It defines such incidents as those “where airline passengers have disrupted flights with threatening or violent behaviour”. The FAA has documented at least 1205 unruly incidents so far this year.
Earlier this year, a 35-year-old Massachusetts man was sentenced to time served and five years of supervised release after spending 26 months in prison for attempting to stab a flight attendant in the neck with a broken metal spoon aboard a United Airlines flight from Boston to Los Angeles in March 2023.
Last year, a man aboard an Alaska Airlines flight from Seattle to Las Vegas was arrested after authorities said he stabbed a fellow passenger with an improvised weapon made of several pens bound together by rubber bands.
