CAIRO, Egypt Authorities arrested an Egyptian chemist who studied in the United States, and they investigated a possible al-Qaeda connection in Pakistan as the search widened for those behind London s suicide bombings, officials said today.
Magdy Mahmoud Mustafa el-Nashar, 33, who was arrested in Cairo, denied any role in the attacks, the Egyptian Interior Ministry said in a statement. He was taken into custody after the July 7 transit bombings and was being questioned, it said.
No charges have been filed against him. London police said a man has been arrested in Cairo, but they would not confirm his name or characterize him as a suspect in the attacks that killed at least 54 people, including four bombers.
Also today, police in Leeds raided a shop selling Islamic books and DVDs just blocks from where at least two of the four suicide bombers lived, and they seized materials.
Muslim leaders have said the young bombers might have been inspired by radical literature. It was not immediately clear whether any of the four bombers had links to the shop, but neighbors speculated that the owner or manager may have met the suspects there.
An earlier search of a flat in Leeds rented by el-Nashar found evidence of explosives similar to those used in the failed 2001 shoe-bombing plot involving Richard Reid, according to The Times of London.
U.S., British and Egyptian officials had been in contact concerning el-Nashar following the blasts, according to an Egyptian government official who spoke on condition of anonymity because he was providing information not in the ministry s statement.
El-Nashar was vacationing in Egypt and had intended to go back to Britain to continue his studies, the ministry said, without specifying the date he was taken into custody.
El-Nashar denied having any relation with the latest events in London. He pointed out that all his belongings remained in his apartment in Britain, it said.
British and FBI officials had been looking for el-Nashar, who recently taught chemistry at Leeds University, north of London.
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 May 6.
FBI agents in Raleigh, N.C., had joined the search for el-Nashar.
North Carolina State University spokesman Keith Nichols said a person named el-Nashar studied there as a graduate student in chemical engineering in early 2000.
Detectives who searched el-Nashar s flat found signs that quantities of a compound called TATP, or triacetone triperoxide, had been converted into a powerful explosive, the Times of London reported.
In 2001, Reid used an improvised shoe bomb rigged with TATP, which is difficult for bomb-sniffing dogs to detect, when he tried to board an American Airlines flight from Paris to Miami and blow it up over the Atlantic.
Reid was subdued by passengers when he tried to detonate the explosive. He pleaded guilty to U.S. charges and is serving a life sentence.
TATP is a highly unstable explosive made from commercially available chemicals.
A spokeswoman for London s Metropolitan Police refused to comment on the report or say what type of explosive was used in the attacks.
Andy Oppenheimer, an explosives expert with Jane s Information Group, said TATP is strong enough to have caused the damage wreaked by last week s bombs.
But he added that making such a highly volatile explosive stable enough to carry out closely synchronized attacks would have required advanced knowledge of chemistry. Police say the three subway blasts happened within a minute.
The New York Times and the British Broadcasting Corp. also reported that TATP was found in a search of a Leeds home.
Earlier, Metropolitan Police Commissioner Sir Ian Blair said investigators were hunting the organizers of the London transit attacks perpetrated by what he called foot soldiers and confirmed police were focusing on a Pakistan connection.
Three of the bombers who carried out last week s terror strikes were Britons of Pakistani descent. Pakistani intelligence officials said today that local authorities are looking into a connection between one of the three and two al-Qaeda-linked militant groups in that country.
Blair told the BBC that police believed they would discover an al-Qaeda connection to the blasts.
What we expect to find at some stage is that there is a clear al-Qaeda link, a clear al-Qaeda approach, because the four men who are dead, who we believe are the bombers, are in the category of foot soldiers, Blair said.
Authorities in Pakistan, meanwhile, were looking into a connection between one of the London suicide bombers and two al-Qaeda-linked militant groups in Pakistan, including a man arrested for a 2002 attack on a church near the U.S. Embassy, two senior intelligence officials said.
The investigation is focusing on at least one trip that 22-year-old Shahzad Tanweer made to Pakistan in the past year, said the officials, who work at two separate intelligence agencies and are involved in the investigation. They spoke to the Associated Press on condition of anonymity because of the secretive nature of their jobs.
One of the officials said that while in Pakistan, Tanweer is believed to have visited a radical religious school run by the banned Sunni Muslim militant group Lashkar-e-Tayyaba.
The sprawling school in Muridke, 20 miles north of Lahore, has a reputation for hostility. Journalists who have traveled to the school in the past have been threatened and prevented from entering.
Lashkar-e-Tayyaba was banned by Pakistan for alleged links to a 2001 attack on India s Parliament.
ABC News, citing unidentified officials, reported that the attacks were connected to an al-Qaeda plot planned two years ago in Lahore.
Names on a computer that authorities seized last year from Muhammad Naeem Noor Khan, an alleged Pakistani computer expert for al-Qaeda, matched a suspected cell of young Britons of Pakistani origin, most of whom lived near Luton, where the alleged suicide bombers met on their way to London shortly before last week s blasts, according to the report.
Authorities have now discovered ties between Mohammed Sidique Khan one of the July 7 bombers and members of that cell who were arrested last year, ABC said.
In another international development in the inquiry, Jamaica s government said it was investigating a Jamaican-born Briton as one of the bombers. Reports identified him as Lindsey Germaine.
On Thursday, police released closed-circuit TV video showing one of the four suicide bombers 18-year-old Hasib Hussain wearing a backpack as he passed through the Luton train station on his way to London.
Hussain allegedly set off the bomb that killed 14 people aboard the bus. That blast occurred nearly an hour after three London Underground trains blew up, and investigators don t yet know what Hussain did during that hour or when he boarded the bus.
Trying to map out Hussain s movements, police appealed for information from anyone who may have seen him in or around King s Cross station, where the four parted ways.
Police officially identified two of the suicide bombers Thursday Hussain and Tanweer, whom they say attacked a subway train between Liverpool Street and Aldgate stations.
News reports have identified the fourth bomber as 30-year-old Mohammed Sidique Khan.
