A suspected Al Qaeda militant has been arrested in connection with the October homicide bombing in Karachi that narrowly missed former Prime Minister Benazir Bhutto but killed about 150 others, a top government official said Wednesday.

Qari Saifullah Akhtar, who has been in Pakistani custody before, was arrested on Monday in Lahore in connection with the bombing that hit Bhutto's homecoming parade when she returned from exile, before her killing in a second homicide attack Dec. 27, Interior Minister Hamid Nawaz said.

"He is involved in the blasts in Karsaz. Therefore he has been arrested," Nawaz told The Associated Press, referring to the Karachi neighborhood where the October bombing happened.
