"Since those arrests, detectives have been working to assess all the evidence we've gathered and to question the men.

"We are working very closely with the premises we identified as the suspected target of the alleged plot, and we continue to provide them with support.
"This has been, and continues to be, a highly complex investigation, and we will not hesitate to take further action if we believe there is any imminent threat to the public.
"I would like to thank the public for their support and understanding - particularly in the areas and communities across the UK who have felt the direct impact of our activity.
