It bears some similarities to the chaos caused on the seafront here a short while ago. Bomb disposal teams were called etc with the whole area including the near side of the main road cordoned off. The package that time turned out to be a rucksack with wiring protruding and a mobile phone..some similarities to the latest story. Nobody was charged for the Dover one.
Could this be some sort of trend, some sort of co-ordinated civil disturbance?
