Deputy Assistant Commissioner Vicki Evans, senior national coordinator for Counter Terrorism Police, said: “This has been a long-running investigation, and part of our ongoing work to disrupt malign activity where we suspect it.
“We fully recognise that the public – and in particular the Jewish community – may be concerned, but I also hope the action we have taken reassures them that we will not hesitate to take action if we think there may be a threat to their safety.”As ever, I would ask them to remain vigilant and if they see or hear anything that concerns them, then to contact us.”
