RIYADH, August 24 (IslamOnline & News Agencies) - A Saudi national suspected of "terror" links by the U.S. Federal Bureau of Investigation (FBI) has turned himself in to Saudi security forces in Riyadh, his father said Saturday.

Abdul Aziz al-Rasheed, father of Saud al-Rasheed, said that his 21-year-old son returned from vacation in Egypt on Thursday and immediately went to the security authorities.

"He is still with the Saudi security authorities," two days after surrendering, the father told Agence France-Presse (AFP).

"He has turned himself in because he is confident he is innocent and we are confident of the fairness of the Saudi authorities," the father added.

He categorically denied that his son has undergone any military training or has ever had any links with Osama bin Laden's Al-Qa’eda network or any other organization.

The FBI on Tuesday released a passport photo of Saud and said it considered him armed and dangerous.

The bureau wanted Saud following recent analysis of evidence collected in the investigation around the September 11 attacks on the United States, carried out mainly by Saudis, that turned up his passport, issued in Riyadh in May 2000.

"He went to Afghanistan only to distribute relief to poor Afghan people and returned months before the September 11 terror attacks," Saud's father said.

He accused Pakistani authorities of handing over his photo and other information to the United States because Saud had gone to Afghanistan through Pakistan.

Saud went to Afghanistan about 19 months ago "as part of a charity relief team" before returning to Saudi Arabia "at least four months before the September attacks," the father said, adding that the FBI photo of his son was genuine.

"My son said he wanted to take part in the relief work and help his brothers in Afghanistan ... I was surprised to see his name and picture in the Internet and media," he admitted.

The father said his son graduated on a computer training course and was briefly employed in the education ministry before starting his own business.

Saud has never traveled to the United States or Europe and had never been linked to a terrorist group, according to his father.

Saud is the 15th person sought in connection with the attacks with hijacked airliners, which killed around 3,000 people in Washington D.C., New York and Pennsylvania.

Thus far, over 500 international prisoners have been arrested since the U.S. offensive in Afghanistan following the events of 9-11.

Another roughly 1,200 Arab and Muslim men living in the U.S. have also been detained and “voluntarily” questioned in relation to the events.
