The FBI announced that Lewis and Bowdich will not elaborate beyond what is alleged in the complaint.
On Friday, four Inland Empire men were arrested in connection to a terrorist plot that was foiled by federal officials.
Sohiel Omar Kabir, 34, an Afghanistan native and former resident of Pomona; Ralph Deleon, 23, of Ontario and a native of the Philippines; Miguel Alejandro Santana Vidriales 21, of Upland; and Arifeen David Gojali, 21, of Riverside, a United States citizen, were arrested on suspicion of plotting to join Al-Qaida and the Taliban in Afghanistan in hopes of killing Americans.
According to the complaint that was filed in U.S. District Court in the Central District of California, the four conspired to provide material support to terrorists in preparation for or in carrying out acts of terrorism.
Three of the suspects had their initial appearance before a federal magistrate Monday afternoon in U.S. District Court in Riverside.
Kabir is in custody in Afghanistan.
