Notice to all Museums Urgent message from William Brown, National Security Adviser, Arts Council I wish to inform all Museums in the UK that the Threat level of an attack on Museums has increased to SEVERE AND IMMINENT All venues are asked to ensure that collections are held in facilities offering the best available defence against any attack. Intruder and case alarms should be used correctly and any alarm trigger treated with professionalism and suspicion ensuring all causes are identified. CCTV systems used should be purged to ensure they are at their optimum performance and good quality images recorded. Staff are advised to be extra vigilant to visitors paying undue attention to collections and ensure all cases are maintained and frequently cleaned to ensure forensic evidence is possible. The practice of checks on the displays of all collections at opening, lunch and closing should be carried out for the foreseeable future. As dark evenings and nights approach rapidly it is a good time to ensure outside lighting is operating and the external aspects of museum buildings checked regularly. In the event of any cause for alarm or an immediate suspicion of people around your venue please do not hesitate to ring 999 and advise the Police of your immediate concerns. Please ensure any information/intelligence is shared with secure circulating and collating networks. Thank you for your attention and action. William continue to be held in the highest security level of cases tate and that increased vigilance should be made of the activity of all visitors.
