London 2012: Police protect torch in Devon and Cornwall
The largest police operation in Devon and Cornwall since the total eclipse of the sun in 1999 is under way ahead for the Olympic torch.
The force said it had set up a major incident plan - or Silver Command - using 200 officers.
The helicopter and armed response units are on standby and control centres have also been set up along the touch route.
The flame is being taken through more than 50 communities across both counties.
Operation commander Supt Chris Singer said: "It's about being prepared and having the resources available to me should I need them."
The first leg saw it pass St Michael's Mount, take a balloon ride over the Eden Project and cross the Tamar Bridge.
It arrived in Plymouth on Friday evening before travelling through Devon on Saturday, reaching Exeter that night.
