A TEENAGER has been arrested in Dover in connection with yesterday's bomb attack on a tube at Parsons Green, West London.
The 18-year-old man was arrested in Dover under The Terrorist Act in connection with the Parsons Green station bombing.
The terror attack saw an improvised explosive device detonated on a London underground tube injuring 29 people.
The man remains in custody at a local police station and will be transferred to a south London police station soon.
Deputy Assistant Commissioner Neil Basu, Senior National Co-ordinator for Counter Terrorism Policing, said: “We have made a significant arrest in our investigation this morning.
"Although we are pleased with the progress made, this investigation continues and the threat level remains at critical.
“The public should remain vigilant as our staff, officers and partners continue to work through this complex investigation. We are not, at this time, changing our protective security measures and the steps taken to free up extra armed officers remain in place.
“This arrest will lead to more activity from our officers. For strong investigative reasons we will not give any more details on the man we arrested at this stage.”
The Prime Minister ordered troops onto the streets on Friday night after a suspected Islamist placed a bomb on a packed train heading towards Westminster.
Witnesses described scenes of terror and panic after the blast sent a “fireball” through a District line service in west London.
Last night the Islamic State terror group claimed responsibility for the attack, according to the Amaq news agency which has links to the group.
The Metropolitan Police have trawled through hundreds of hours of CCTV footage and 77 images and videos taken by the members of the public to try to identify who committed the atrocity.
Mrs May said: “The public will see more armed police on the transport network and on our streets, providing extra protection.
“This is a proportionate and sensible step which will provide extra reassurance and protection while the investigation progresses.”
Parsons Green tube reopened on Saturday morning.
Peter Crowley posted a photo of his ‘charred head’ on social media.
He said: “I would personally say roughly about 20 who had physically injuries a lot of people who were shaken by the incident.
“I wasn’t aware of the bag, I tend to keep myself to myself, I was side on to where I believe the incident happened.
