Security forces have arrested Omar Bakri (search), the Islamic cleric being investigated in Britain on terror-related charges, officials said Thursday.

The officials, who spoke on condition of anonymity because they weren't authorized to speak about the case, refused to say when or where Bakri was arrested.

The local Future TV channel reported that Bakri was arrested Thursday afternoon as he left its building in the west Beirut district of Raouche after giving an interview.

The station said Bakri was told that the General Security department wanted to question him about "information regarding his entry into Lebanon."

Bakri, who earned a reputation for extremism during his 20 years in Britain, announced Tuesday that he was in Lebanon. The cleric said he was visiting relatives but planned to return to Britain within six weeks.

Bakri founded the now-disbanded radical Islamic group al-Muhajiroun (search), which came under scrutiny in Britain, particularly after some of its members praised the Sept. 11, 2001, attacks on the United States.

Bakri is from Syria, but his wife's family is Lebanese and he has citizenship in both Syria and Lebanon.
