Police said the man, who belongs to Islamabad's radical Red Mosque and a group based in the Orakzai tribal region bordering Afghanistan, was wanted for a string of attacks.
"Five blasts took place in Islamabad in 2009, four of them have been investigated and he is involved in all four of those blasts," Islamabad police chief Kalim Imam told a press conference.
One of those attacks was the 5 October strike on the offices of the World Food Programme in Islamabad in which five UN workers were killed.
"He brought the man to the World Food Programme (office)," said Imam.
Police seized suicide jackets, about eight kilogrammes of explosives and ball bearings used to make bombs in his possession.
A US missile attack has killed eight people, including foreign militants in the district of Mir Ali, north-east of Miranshah, the main town of the restive North Waziristan tribal district.
"At least eight people were killed in the drone attack. A compound used by militants was targeted," a senior security official told AFP.
Another security official described the target as a Taliban training centre in Palooseen village. There were foreigners among the dead, the official said, using a term employed widely in Pakistan to mean Al-Qaeda operatives.
Pakistani military officials said a foreign "terrorist" named Salah al-Somali was the target but there was no confirmation on whether he died or not.
In Peshawar, meanwhile, three policemen were killed when a bomb packed with steel pellets struck their patrol vehicle shortly after midnight on Thursday.
It was the second attack in the city in less than 24 hours, after a suicide bomber blew himself up outside a court building, killing 20 people.
