RALEIGH , North Carolina ( CNN ) -- Men arrested last week on suspicion of plotting a `` violent jihad '' overseas had weapons , thousands of rounds of ammunition and $ 13,000 cash in their home , an FBI agent testified in court Tuesday . An FBI agent testified he considers Daniel Patrick Boyd and six others `` a risk of flight '' who should be denied bail . Also found at the home of Daniel Patrick Boyd and his sons were gas masks and a book that FBI special agent Michael Sutton called `` essentially our playbook to how we respond to acts of terrorism . '' The seven men arrested last week should not be released on bail , he said . `` I think all of them are a risk of flight , your honor , '' Sutton testified , noting allegations that all the defendants had traveled overseas . All face charges of supporting terrorism and conspiracy to commit murder abroad . Authorities are seeking an eighth suspect in the case . Officials identified three of the men as U.S. native Daniel Patrick Boyd , 39 -- who had fought against the Soviets in Afghanistan -- and Boyd 's sons , Dylan Boyd , 22 , also known as `` Mohammed , '' and Zakariya Boyd , 20 . The four others are : Mohammad Omar Aly Hassan , also a U.S.-born citizen ; Hysen Sherifi , identified as a native of Kosovo who is a legal permanent resident of the United States ; and Ziyad Yaghi and Anes Subasic , both naturalized U.S. citizens . Sabrina Boyd -- the wife of Daniel Patrick Boyd and the mother of the two younger Boyds -- said last week the allegations against her family are false . `` I know that my husband and my sons are free of guilt , '' she told CNN on July 28 , when they were arrested . `` I 'm hopeful that the truth will come to light . '' Watch Sabrina Boyd state her family 's innocence » . Sutton testified Tuesday that Daniel and Dylan Boyd were arrested in Durham , North Carolina . Both were carrying weapons , and had permits to do so . The arresting agent told Sutton that Daniel Boyd attempted `` to acquire his sidearm , '' and that Dylan Boyd `` failed to comply with their instruction and had to be subdued . '' In a later interview , the younger Boyd told Sutton he had not gone for his gun . Five surreptitiously recorded audio tapes were played in the hearing , along with a cell phone video showing someone firing an AK-47 . On a tape made in May 2009 , the elder Boyd talks about getting the money needed to wage jihad and hitting Wells Fargo trucks and banks . He makes reference to how he had robbed a bank in Pakistan . In the search of the Boyd home the FBI says agents found : . • Several weapons ; . • 27,000 rounds of ammunition , including some armor-piercing types ; . • $ 13,000 in cash . In addition , Dylan Boyd had a deposit slip for $ 16,000 ; . • Four gas masks ; . • A book called `` Emergency Response to Terrorism , '' which Sutton said would be useful to someone trying to counter law enforcement ; . • A document described as a fatwa ( Muslim religious edict ) of jihad ( holy war ) against America . It includes the assertion that the killing of Americans and their allies `` is an individual duty for every Muslim . '' • An old identification card . Sutton said an FBI linguist says it reads `` monotheism , jihad and power . ... No God but God . Mohammed is his messenger . '' On the flip side it says that the carrier is allowed into a certain house alone but should surrender the card when leaving . They also found a trench under the deck of the house , which a witness told the FBI was a bunker to store and conceal weapons , and a plywood plank placed in a tree so that someone sitting there could see anyone approaching the house , according to Sutton . The indictment against the men makes no reference to a direct threat to individuals or property in the United States , but said the men had practiced military tactics in a North Carolina county that borders Virginia .
