A security chief has called for the public to help be their 'eyes and ears' in the fight against terrorism by remaining vigilant.
Richard York, director of Norse Security Services, said police and security firms will take every precaution to prevent attacks like the bombing in Manchester.
He said: 'The public can be assured that event organisers, their security providers and the police, will have been involved in very methodical, in-depth planning around such risks from the outset.
'In the light of the terrible atrocity in Manchester on Monday evening, it is imperative at any event that the public are ever more vigilant.
'If they feel at all uncomfortable with people around them, suspicious packages or activity, they should inform their nearest steward, security person or member of the police force immediately.
'Often the public are a vital extension of our own eyes and ears.'
