LONDON, July 30, 2005 (IslamOnline.net & News Agencies) - British police Saturday, July 30, grilled suspected bombers wanted in the July 21 botched attacks, as they made more arrests aiming to pin down any links to a wider network that they fear could strike again.

Forensic experts are further scouring an apartment block in west London where two of the four suspected bombers were seized in a dramatic raid Friday, July 29, in what the British press touted as a major success for Scotland Yard in the fight against terror, reported Agence France-Presse (AFP).

All four fugitives were now behind bars, three in London and one in Rome, facing an extradition hearing later in the day.

Of the two suspects arrested in west London on Friday, Eritrean-born Muktar Said Ibrahim, 27, is accused of trying to blow up a Number 26 double-decker bus.

The second, Ramzi Mohammad, is suspected of trying to set off his device in The Oval Underground train station.

A third, 24-year-old Somali-born Yassin Hassan Omar, was detained in a raid in the central city of Birmingham on Wednesday, July 27.

He is wanted for the attempted bombing of a Victoria Line train near Warren Street.

The domestic Press Association reported that a third man arrested Friday in Tavistock Square, west London, was Ramzi's brother Wahbi Mohammad, 23.

Sky television station quoted unnamed sources as saying Wahbi was a fifth bomber responsible for an unexploded device which police found in a west London Park on July 22.

More arrests were made Saturday under anti-terror laws in separate pre-dawn operations in Leicester, north of London.

Police said the arrests were not necessarily connected to the July bombings.

Metropolitan Police anti-terrorist chief Peter Clarke said that despite the arrests the terror threat was not over and police remained on high alert.

"We must not be complacent. The threat remains and is very real".

The three suspects captured in Britain face at least two weeks of tough interrogation and grim prison conditions at the country’s highest-security police station, Paddington Green.

"You're completely cut off. Mentally it's really tough. It could break anyone," 42-year-old John, an ex-soldier and one-time Paddington Green detainee, told the Daily Mirror newspaper.

"When you arrive, you're locked in a 15 foot by 10 foot cage like an animal."

The first arrested suspect has been there since Wednesday.

"Omar will be locked in a bright, white, 12 foot by 10 foot (three meter by 3.7 meter) cell with a steel toilet by the door and watched on closed circuit television," John said.

"The bed is a concrete slab with a plastic mattress; it doesn't matter, you can't sleep. There are strip lights on 24 hours and no natural light."

Louise Christian, who represented former Guantanamo Bay detainees, said police will rely on the "good cop, bad cop" routine.

"One starts off being nice and reasonable and tries to get them to chat. Then the other comes in later and by being quite rude and offensive tries to provoke and shock the suspect into speaking," she told The Independent.

Under Britain's Terrorism Act 2000, police can hold suspects for up to 48 hours without a judicial warrant.

Suspects must be allowed to sleep for eight hours in every 24 and provided with refreshments.

Hussein faces an extradition hearing in Rome Saturday. (Reuters)

Osman Hussein, the suspected bomber arrested in Rome Friday, will face an extradition hearing later Saturday, a judiciary source said.

Italian newspapers Saturday said he admitted that himself and his accomplices wanted their attack to spread fear in London.

"We wanted to make an attack, but only as a demonstration," several newspapers quoted 27-year-old Hussein as saying, without citing a source.

"I came to Rome because I didn't know where else to go and because I had friends here and could find a place to stay," La Repubblica quoted the suspect as telling police.

"I would have stayed here for a while and then gone elsewhere. I don't know of any plan to attack Italy."

Several newspapers expressed fears that the presence of one of the presumed London bombers could be linked to a planned attack in Italy.

Italian police on Saturday carried out a series of raids on the homes of people known to Hussein after Interior Minister Giuseppe Pisanu told a special session of parliament that the suspected bomber had a network of contacts in the Ethiopian and Eritrean community in northern Italy to help him evade capture.

Pisanu further revealed that Hussein was of Ethiopian and not Somali origin, adding that he left London by train on July 26, five days after the bungled bombings.

Italian police moved in to arrest Hussein after tracking his mobile phone through France and Italy before his arrival in Rome by train.

British police had provided their Italian counterparts with the phone number, which was initially tracked to the Waterloo Station area of London on Monday but then went silent. The signal was picked up again in Paris on Wednesday, and then again in Milan and Bologna on Thursday.

Police in Rome, meanwhile, mounted round-the-clock surveillance on Hussein's brother, who owns a phone and Internet center near Rome's Termini Station.

He eventually led them to the flat in the eastern Rome suburb where Hussein was arrested.

Among a number of people detained for questioning late Friday by Italian police was Tunisian Mohammad Bin Mohammad, an official at a mosque near Hussein’s flat.

As the investigation's reach extended overseas, British police have not confirmed that they are seeking a man, Haroon Rashid Aswat, who is reportedly being held in custody in Zambia.
