Sargodha , Pakistan ( CNN ) -- The mother of one of the five young men arrested in Pakistan told CNN Thursday that her son was in that country to get married , not to plot terror attacks as Pakistani police have alleged . The FBI was in Pakistan on Thursday interrogating the men , who some U.S. and Pakistani law enforcement officials have identified as Americans , according to Usman Anwar , head of the district police of Sargodha , about 120 miles south of Islamabad . The five had been reported missing from Virginia , and police are confident they were planning terrorist acts , Tahir Gujjrar , deputy superintendent of police in Sargodha , told CNN on Wednesday . Pakistani authorities said they believe the young men tried to connect with militant groups . In an interview with CNN , Subira Farouk said her son , Umar , was one of the young men detained in the case . She said her husband also was arrested , which would bring to six the number of people in custody . Police confirmed they have six people in custody , not five , as was originally reported . Farouk said her son would never plot a terror attack . She described him as a business student at George Mason University in suburban Washington . Farouk said she and her husband went to Pakistan to arrange a marriage for their son , who surprised her by traveling from the United States . The arrests came after a raid Wednesday on a home in Sargodha , Gujjrar said . Investigators found laptops and maps of Pakistan containing highlighted areas that correspond to regions where terrorists have been active , Anwar said . It is too premature to link the men with any terrorist organizations , he said , but preliminary investigations suggest they had sought to link up with the Jaish-e-Mohammed and Jamaat ud Dawa militant organizations . Neither group showed interest , he said . President Obama said Thursday that he envisioned `` a series of investigations '' into the arrests . `` I think the details are still forthcoming , '' Obama said . `` There will undoubtedly be a series of investigations surrounding these events , so I 'd prefer not to comment on them at this point . '' Farouk said her son mentioned that he planned to go to a conference with friends . She said she did not hear from him , grew concerned and began calling his friends ' parents . That 's when she realized that he and his friends were missing . She said she thought they had been kidnapped . Their families contacted the Council on American Islamic Relations and U.S. law enforcement authorities . Farouk said the authorities advised her to stay in Pakistan . Later , Farouk said she got a call from a relative in Pakistan who said her son was in the country with several friends . She said she was relieved , thinking her son had surprised her , but then authorities arrested her husband , her son and his friends . The U.S. law enforcement official said none of the five missing men had shown up on law enforcement 's radar before they were reported missing . Authorities believe their intent was to wage jihad overseas rather than in terrorist acts in the United States , the official said , but `` there is still a lot of uncertainty about what they were up to .
