NYT–LONDON — The Kenyan authorities were reported on Monday to be planning to deport a Jamaican-born Muslim cleric, Abdullah el-Faisal, who may have helped inspire the Nigerian man accused of trying to bomb an American airliner headed to Detroit on Christmas Day.
Mr. Faisal has long been known to law enforcement agencies in the United States and Europe. He was tried in Britain in 2003 on charges of spreading racial hatred and urging his followers to kill Christians, Hindus, Jews and Americans. He was deported from Britain in 2007.
Reuters reported from Nairobi, the capital, that Mr. Faisal was in Kenya on a preaching tour. But intelligence officials feared that his speeches would encourage radicalism in a country that has been a target of attacks ascribed to Al Qaeda, including the 1998 bombing of the American Embassy. He was arrested Sunday in the port city of Mombasa.
“The minister in charge of immigration has declared him as an unwanted immigrant. We don’t want him in this country,” a police spokesman, Eric Kiraithe, told Reuters. It was not clear when Mr. Faisal would be deported.
“From what he says, he was coming to preach,” Mr. Kiraithe said. “The contacts he was maintaining, according to our intelligence, are not the best, are not in our national interests.”
Mr. Faisal settled in Britain in the early 1990s and became imam of the Brixton mosque in South London, which was reported to have been frequented by Richard C. Reid, the so-called shoe bomber who sought to blow up an airliner bound for the United States just before Christmas in 2001.
Abdul Haqq Bakr, the chairman of Brixton Mosque and Islamic Cultural Center, said at the time that Mr. Reid had joined prayers at the mosque in late 1995 and left in 1998.
Zacarias Moussaoui, who was sentenced in the United States in 2006 to life in federal prison after he admitted knowledge of the Sept. 11, 2001, plot, also prayed at the Brixton mosque.
Mr. Faisal, a Jamaican-born convert to Islam who studied in Saudi Arabia, was found guilty in 2003 of encouraging followers to use chemical and nuclear weapons against their enemies from other faiths. He was sentenced to seven years in prison.
He was deported four years later after the authorities accused him of influencing Germaine Lindsay, one of the four attackers in the London bombings of July 2005. Mr. Lindsay was also a Jamaican-born convert to Islam.
Mr. Faisal’s name surfaced much more recently in investigations into Umar Farouk Abdulmutallab, the Nigerian man accused of the attempted attack on a Northwest Airlines flight.
In an online posting in May 2005, under the name “farouk1986,” Mr. Abdulmutallab referred to Mr. Faisal as a cleric he had listened to, according to American military and law enforcement authorities.
In his posting, Mr. Abdulmutallab wrote: “I thought once they are arrested, no one hears about them for life and the keys to their prison wards are thrown away. That’s what I heard Sheik Faisal of U.K. say (he has also been arrested I heard).”
It was not clear how Mr. Faisal had made his way to Africa after being deported to Jamaica in 2007. The Kenya newspaper Daily Nation quoted the immigration minister, Otieno Kajwang, as saying that he entered Kenya from Tanzania using a border post at Lunga Lunga that was not connected to a central database in Nairobi.
Daily Nation reported Sunday that Mr. Faisal has previously been denied entry into Kenya.
He had traveled to Nigeria, Angola, Mozambique, Swaziland, Malawi and Tanzania before arriving in Kenya, the newspaper said. He was arrested after attending prayers at a mosque.
The newspaper quoted Mr. Kajwang as saying: “We are not deporting him because he is a Muslim. We are deporting him because of his terrorist history and the fact that he is on the international watch list. ”
