Pakistani police claim they detained some Islamic militants who may have had links with the suspects in the London suicide bombings, which left 56 people dead.
The revelation came a day after a senior immigration official said three of the four suspected bombers traveled last year to the southern port city of Karachi. All three were Britons of Pakistani origin, says the AP.
Security officials believe one of the bombers spent time at a seminary in the eastern city of Lahore, and the police chief there, Tariq Saleem, said some people were in custody.
"We are holding a few militants who are suspected of having links to the London suicide bombers," said Saleem, who did not name the suspects. He said officers were trying to find out whether the "London bombings have any tentacles in Pakistan, especially in Lahore."
Pakistani security forces detained 25 suspected Islamist militants in a series of raids overnight, reports Reuters. The latest detentions were made in an overnight crackdown in the most populous province, Punjab, and included members of outlawed Islamist groups.
"They are being questioned for links with any of the bombers," an official of the provincial government told Reuters, speaking on condition of anonymity.
A person, whom British terrorists attempted to hire as a suicide bomber, shared his information with the press. The man's story proved the supposition of London investigators, who assumed that there were more than just four young suicide bombers on Al-Qaeda's list.
