A 20-year-old man has been arrested after a hoax device was found near an official G7 summit site.
The Falmouth Hotel and neighbouring buildings were evacuated in the early hours of Thursday after the suspicious package was found on grounds outside.
Devon and Cornwall Police said the man, from Falmouth, has been taken into custody.
Some 100 people were moved from the affected properties while a 328ft (100m) cordon was put in place.
The device was declared safe by a Royal Navy Explosive Ordnance Disposal team.
The town is hosting the international media centre for the G7 summit, which will begin in Carbis Bay on Friday.
Devon and Cornwall Police tweeted that officers were called to the hotel in Cliff Road at about 03:15 BST.
The cordon was removed by 06:30 BST and residents were allowed to return to buildings.
A police spokesperson tweeted: "A smaller scene guard will remain in place until the item is collected and removed by scenes of crime."
