British police have arrested a man in connection with the failed bomb attacks in London on July 21st, saying he had been held by anti-terrorism officers as he stepped off a plane from Ethiopia.
The 23-year-old man, from the Tottenham area of north London, was arrested on suspicion of the "commission, preparation or instigation of acts of terrorism" as he left the plane from Addis Ababa at London's Gatwick Airport.
The man, who has been out of the country since June, has been taken for questioning at a central London police station. A house in Tottenham was searched last Friday but no further homes are currently being investigated, a police spokeswoman said.
Detectives say four men tried to set off bombs on three underground trains and a bus in the capital on July 21st but their devices failed to detonate.
The botched attacks came just two weeks after four British Islamists killed themselves and 52 others in an identical plot in the British capital.
A police source said the arrested man was thought to be involved in the logistical side of the alleged plot and his links to the other suspects are now being investigated.
"At this stage we are not suggesting he would have been a fifth bomber," the source said.
Four men appeared in court earlier this month accused of planning to carry out the July 21 attacks whilst 11 others have also been charged in connection with the attempted bombings.
