“Detectives are carrying out extensive inquiries to determine the full facts behind the attack.
“We anticipate that the searches will take some days to complete and may cause further disruption.
“However, it is important that we continue with these searches and I’d like to thank all those affected for their support, patience and cooperation.”
He added: “As police and our partners do all we can to confront the threat, public vigilance remains as vital as ever.
“We urge the public to report any suspicious activity to the police by calling us, in confidence, on 0800 789 321, or in an emergency by dialling 999.
“We are asking the public to look out for anything that seems out of place, unusual or just doesn’t seem to fit in with day-to-day life. It may be nothing, but if you see or hear anything that could be terrorist-related trust your instincts, then act, and call us.”
