Police yesterday arrested an Egyptian biochemist sought in the probe into the London bombings, a government official said.
Magdy el-Nashar, 33, was arrested in Cairo early yesterday, the official said, speaking on condition of anonymity because an official announcement of the information had not yet been made. El-Nashar was being interrogated by Egyptian authorities, the official said.
Metropolitan Police in London said a man had been arrested in Cairo, but would not confirm his name or characterize him as a suspect. The British Embassy in Cairo said it had not comment beyond the Metropolitan Police statement.
British and FBI officials were looking for el-Nashar, who recently had been teaching chemistry at Leeds University, north of London. The Times of London said el-Nashar was thought to have rented one of the homes police searched in Leeds in a series of raids Tuesday. Neighbors reported el-Nashar recently left Britain, saying he had a visa problem, the newspaper said.
Leeds University said el-Nashar arrived in October 2000 to do biochemical research, sponsored by the National Research Center in Cairo, Egypt. It said he earned a doctorate on May 6.
FBI agents in Raleigh, North Carolina, joined the search for el-Nashar, who was formerly a North Carolina State University graduate student.
University spokesman Keith Nichols said a person named el-Nashar studied at North Carolina State as a graduate student in chemical engineering for a semester beginning in January 2000. Nichols said the school has gathered records in anticipation of being contacted by the FBI.
Meanwhile, the link between the London bombings and al-Qaeda grew yesterday, as it emerged that the explosives used in the British capital "might be similar to those seen in earlier operations by the terror network.
As the confirmed death toll from the July 7 bombings rose to 54 with the death of an Australian man, investigators were hoping that fuzzy security camera images of one of the bombers, aged just 18, would encourage more witnesses to come forward.
Metropolitan Police Commissioner Sir Ian Blair confirmed on BBC radio that there was "a Pakistan connection" to the bombings, in which three of the four suspected perpetrators were Britons of Pakistani origin.
But he added: "There are also connections in other countries."
"What we expect to find at some stage is that there is a clear al-Qaeda link, a clear al-Qaeda approach," he said.
"The four men who are dead and who we believe to be the bombers -- though we have only confirmed two identities absolutely -- are in the category of foot soldiers," he said.
"What we've got to find is, who encouraged them? Who trained them? ... Those are the things in which we are now so interested," he said.
Blair branded the bombings, which also injured 700 people, as the single worst instance of mass murder in English history.
BBC television's Newsnight program said that evidence of acetone peroxide, an explosive substance, had been found at a home in Leeds linked to one of the four bombers.
It was the same type of explosive that al-Qaeda "shoe bomber" Richard Reid tried to detonate on a Miami-bound flight in December 2001, three months after the Sept. 11 attacks in the US that killed some 3,000.
Blair, the most senior police officer in the nation, did not deny the report, which he described as "reasonably fair."
