Three more men have been arrested in South Wales connection with last week’s attack on a London commuter train near Parsons Green underground station.
The first, a 25-year-old, was detained in Newport on Tuesday night, while two more men, aged 48 and 30, were arrested in the early hours of Wednesday morning, during a search at an address in the city.
Searches at two addresses in Newport were ongoing, according to police.
In what has been described as a “fast moving investigation”, police are questioning an 18-year-old arrested at Dover on Saturday and a 21-year-old detained in West London.
The home made bomb sent flames shooting through a packed railway carriage during Friday morning rush hour. Thirty people were injured.
It’s the fifth major attack regarded as a terrorist incident in Britain this year. Self-styled Islamic State has claimed responsibility but police say there is no evidence of direct IS involvement.
