Karachi, Sept 15: US and Pakistani agents who are interrogating top terror suspect Ramzi bin al-Shaiba and other al Qaeda members have seized evidence in their hunt for more operatives, a Pakistani intelligence official said today. He said the investigators returned last night to two bungalows where some of the suspects were arrested last week.
"The most vital thing they got is a telephone index and an office file containing printouts of some e-mails," the official told reporters on condition of anonymity.
The Federal Bureau of Investigation (FBI) is firmly in charge of the investigation, he said.
"The Pakistani intelligence officials have been asked to hand over all such information to the FBI and work in accordance with guidelines they receive from the Americans," the official said.

"These FBI officials are interrogating the suspects according to their methods and even not allowing Pakistani intelligence to interfere. The Pakistanis are supposed to extract maximum information from the low-key suspects and convey it to the FBI men," the official said.
Bin al-Shaiba, described by President George W. Bush a "one of the planners and organisers" of the devastating September 11 attacks in the us, was among several al Qaeda members arrested last week in this southern city. Bureau Report
