A Brixham restaurant was evacuated by emergency services after “unexploded grenade fuses” were found nearby.
Hundreds of customers were told to leave Rockfish and vacate the area after the devices were discovered around 2pm.
A picture of the scene, taken by diner Kirsten Clarke, showed four marked police vehicles parked outside the restaurant, which overlooks the harbour.
A spokesperson for Devon and Cornwall Police said it is believed the devices were dredged up by a boat.
Updates on this incident, which is ongoing, will be published below.
