PAKISTANI security officials have interrogated six people with contacts with the family of one of the London suicide bombers, clearing them of links to the attacks. Phone calls had been made to some Pakistanis from the house of one of the bombers. Three of the four attackers were British nationals of Pakistani origin. The British Government gave Pakistan the names and telephone numbers of some individuals following the July 7 attacks that killed at least 55 people, a security official said on condition of anonymity.Security officials said they had interrogated six people about their links to the family of Shahzad Tanweer.
"We have established that these people had business contacts with the family of Tanweer back in London," a senior security official said.
"The six interrogated are all cleared now. The telephone calls were made only for business purposes and they were not linked in any way to the attacks."
The three ethnic Pakistani bombers recently visited Pakistan and investigators are probing whether they met al-Qaeda-linked militant groups.
A senior immigration official in Karachi said Tanweer, 22, and Mohammad Siddique Khan, 30, flew to Karachi last November 19, and left on February 8 this year for Britain.
Hasib Hussain, 18, arrived in Karachi on July 15, 2004 from Riyadh.
The immigration official said there was no record of him leaving Karachi, but he could have flown out via Lahore or Islamabad.
"So far we have not found the links of Tanweer and Khan to Hussain, but it could be possible that they were on different assignments," a Karachi-based intelligence official said.
Foreign ministry spokesman Jalil Abbas Jilani, however, said he had no information the three bombers had travelled to Pakistan.
