Teenager 18-year, was arrested by Kent Police in the port area of Dover this morning, Saturday, 16 September, under section 41 of the Terrorism Act,” police said in a statement.
“The man remains in custody at a local police station. He will be transferred to a south London police station in due course.
“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,” Deputy Assistant Commissioner Neil Basu, Senior National Coordinator for Counter Terrorism Policing, said. Further, Basu advised the public to “remain vigilant” and said their “complex investigation” into the attack is ongoing.“We are not, at this time, changing our protective security measures and the steps taken to free up extra armed officers remain in place,” he added.
The Islamic State group has said it was behind the bomb but Met Police’s Assistant Commissioner Mark Rowley said it was very routine for ISIS to claim the attack, whether in contact with those involved or not.
Prime Minister Theresa May announced the UK terrorism threat level was raised from ‘severe’ to ‘critical.’ ‘Critical’ is the highest threat level.
“Military personnel will replace police officers on guard duties at certain protected sites that are not accessible to the public,” May told media.
