A sixth man has been arrested in Britain in connection with a suicide bombing in Tel Aviv earlier this week.
He was held at an address in London and taken to a police station in the city centre, where he joined two men and three women arrested during raids in Derbyshire and Nottinghamshire yesterday.
A Scotland Yard spokesman refused to confirm whether any family members of Omar Khan Sharif, the 27-year-old from Derby who is alleged to have fled the scene of the bombing after his device failed to detonate, have been arrested.
All six were arrested under section 41 of the Terrorism Act 2000, which relates to those suspected of being involved in the commission, preparation or instigation of acts of terrorism.
Police were searching addresses in the Midlands. No weapons or any explosive devices are believed to have been found.
The arrests follow a joint British and Israeli security services operation to establish how a British Muslim became a suicide bomber.
Israeli police claim Asif Mohammed Hanif, 21, of Hounslow, west London, detonated a device in the doorway of Mike's Place, a bar in Tel Aviv, in the early hours of Wednesday, killing three other people.
Authorities are still hunting for his alleged accomplice, Omar Khan Sharif.
