An Iranian woman who resides in Southern California was arrested on suspicion of “trafficking arms on behalf” of the Iranian government, an official said on Sunday, April 19.

Shamim Mafi, 44, was arrested at Los Angeles International Airport on April 18, said Bill Essayli, first assistant U.S. attorney for the Central District of California.

According to a criminal complaint, Mafi is accused of having “conspired with others to perpetrate an unlawful scheme to broker the sale of weapons, weapons components, and ammunition on behalf of the Government of Iran,” violating the International Emergency Economic Powers Act.

The International Emergency Economic Powers Act gives the president “broad authority to regulate a variety of economic transactions following a declaration of national emergency,” according to the Congressional Research Service. President Donald Trump has used this law to impose sweeping tariffs.

According to the complaint, Mafi, with the assistance of an unnamed co-conspirator, “brokered the sale of 55,000 bomb fuses to the Sudanese Ministry of Defense.” In addition, they “brokered the sale of millions of rounds of ammunition from Iran to Sudan.”

Mafi is accused of brokering weapons deals on behalf of Iran through a company she owns with a co-conspirator as recent as early 2025, according to the complaint. That includes one contract valued at over 60 million euros for a sale of Iranian-made drones to Sudan’s ministry of defense, according to the complaint. Other items that Mafi brokered, or attempted to broker, included “bombs” and “assault weapons,” according to the complaint.

Essayli said that Mafi is expected to make her first court appearance on April 20. It’s not immediately clear who represents Mafi.

According to the complaint, Mafi was born in Iran but is a lawful permanent resident of the United States and maintains a residence in Woodland Hills of Los Angeles.

She frequently traveled to and from Los Angeles, and Mafi “only spends part of her time” in the U.S., according to the complaint.

Mafi faces a maximum sentence of 20 years in federal prison if convicted, according to Essayli.
