LONDON – An 18-year-old man was arrested in the port area of Dover on Saturday morning by police investigating the Parsons Green terror attack.
Kent Police made the arrest and the man remains in custody at a local police station. He will be transferred to a south London police station, police said.
Meanwhile, armed police have evacuated and are searching a residential address in Sunbury, Surrey.
“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,” Neil Basu, senior national co-ordinator for counter terrorism policing, said in a statement.
“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,” he said.
The UK’s terror threat level has been raised to “critical” after an improvised explosive device on a London Underground train injured 29 people on Friday, Prime Minister Theresa May said.
May said that the device was “intended to cause serious harm,” while The Times reported earlier it was a nail bomb.
The threat level is the UK’s highest and indicates that authorities believe another attack is imminent.
“Hundreds” of officers from London’s Metropolitan Police have been deployed in the hunt for the perpetrators of the attack on Parsons Green station London on Friday morning, a senior officer said.
Detectives have spoken to 45 witnesses and continue to receive information from the public to the confidential anti-terrorist hotline.
