Q295: What do I do if I see a suspicious package on the train/ at the airport /in a shopping centre?
If you see what you believe to be a suspicious package, notify someone in authority immediately, a security guard, police officer. They will then be able to take the appropriate action.
Do not touch or move the package yourself. Although it is likely to be a harmless package you should not interfere with it in any way for your own and others safety.
