An 18-year-old man was arrested Friday afternoon in connection with terrorism charges, officials said.

Mahin Khan was taken into custody following a joint operation between the Arizona Attorney General's Office and FBI, said Mia Garcia, a spokeswoman for the Attorney General's office.

"Khan allegedly conspired to commit acts of terror against government buildings in Pima and Maricopa County," Garcia said.

He's being held in the Maricopa County jail with no bond on one count of conspiracy to commit terrorism and one count of terrorism, she said.

Khan appeared before a judge Saturday morning. It's unclear if he has an attorney yet.

All records relating to the case have been sealed, so no details are currently available, Garcia said.

"The Arizona Attorney General's Office and FBI are not aware of any threats Khan made against the Fourth of July," Garcia said. "The timing of his arrest has nothing to do with the holiday."
