A California tech executive accused of illegally supplying advanced US networking and encryption equipment to Iran’s nuclear and military institutions for more than a decade has been arrested at his luxury ocean-view mansion, according to the US Justice Department.Jamshid Ghomi, 63, is a dual Iranian-American citizen. He was taken into custody at his $35 million Newport Beach estate and charged with conspiracy to violate the International Emergency Economic Powers Act. Authorities allege he helped deliver sensitive technology to Iran and its Defense Ministry through a long-running smuggling operation.They are accused of using middlemen to route purchases and shipments to the UAE, including more than 400 transactions made through eBay and PayPal between 2011 and 2015. Prosecutors say more than 250 metric tons of networking equipment was smuggled into Iran through Dubai-based freight forwarders between 2014 and 2018.Ghomei ran the operation through his own company, Faraz Pardaz Rayneh (FPR), which generated over $10 million in annual sales. Investigators also claim the company supplied Iran’s Defense Ministry between 2014 and 2022 and its nuclear agency from 2017 to 2023.Authorities further alleged that Ghomei transferred more than $15 million from Iran to US accounts, misrepresenting it as foreign inheritance. The money was laundered through shell companies in the British Virgin Islands, Hong Kong, Türkiye and the United Arab Emirates.Ghoomi’s personal tax filings showed almost no income, his highest annual income was $20,684, and he claimed earned income tax credits in seven different years, regardless of his reported wealth.The case also reflects the scale of his wealth. Ghomei bought a vacant lot in March 2010 for $4.49 million and later spent about $10.49 million building a 14,000-square-foot mansion overlooking the Pacific Ocean, the California Post reported. More than $7 million in foreign wires linked to his company flowed into the account that was used to finance the construction.Iran’s nuclear agency was sanctioned by the US in 2020 and later registered FPR as an approved vendor in 2021 and 2022.First Assistant U.S. Attorney Bill Essayli said: ‘We will hold him accountable by seeking an appropriate prison sentence and seizing his assets, including his $35 million Newport Beach mansion.’Essaly also said Ghomei was ‘assisting our declared enemies’ and ‘doing business with one of the world’s largest state sponsors of terrorism.’Ghomei was scheduled to appear in court in Santa Ana, Orange County, and faces up to 20 years in prison if convicted.
