Third man arrested in connection to London Tube bucket bombing

A third man has been arrested in connection to last week’s London Tube bucket bombing that left 30 people injured.

A 25-year-old man was arrested at a home in Wales shortly after 7pm local time, Scotland Yard said in a statement.

He was charged under section 41 of the UK’s Terrorism Act.

Two other men have also been charged in connection to Friday’s rush hour bombing at Parsons Green station and remain in police custody.

Police arrested an 18-year-old man in the departure lounge of Dover port early on Saturday in what they called a "significant" step and then raided a property in Sunbury, a town near London while a second man, 21, was arrested later that evening

The home-made bomb shot flames through a packed train carriage at west London's Parsons Green Tube station during the Friday morning rush hour but apparently failed to detonate fully.

Islamic State claimed responsibility, as it has for other attacks in Britain this year, including two in London and one at a concert by American singer Ariana Grande in Manchester in May.

Home Secretary Amber Rudd said the second arrest indicated it was not a "lone-wolf" attack, but there was no evidence Islamic State was involved.

"It is inevitable that so-called Islamic State, or Daesh, will reach in and try to claim responsibility. We have no evidence to suggest that yet," she told the BBC's Andrew Marr Show.

"But as this unfolds, and as the police do their investigations, we will make sure that we find out exactly how he was radicalised, if we can."
