Police investigating the failed 21 July London bomb attacks have charged a man with conspiracy to cause explosions.
Shepherd's Bush was one of the targeted stations
Adel Yahya, 23, was arrested at Gatwick Airport on Tuesday, after arriving on a flight from Addis Ababa, Ethiopia.
The student from north London is due at Bow Street magistrates on Friday.
Five men have already been charged with conspiracy to murder following the failed attacks, which came two weeks after the July 7 bombings.
Police charged Mr Yahya after being granted extra time to question him on Thursday.
He was arrested by anti-terrorism police, supported by Sussex officers, under the Terrorism Act 2000.
Scotland Yard said it believed he had been out of the UK since June.

Dozens more people have been questioned under the Terrorism Act but released without charge.
