Sonar scans show that 'UFO' at bottom of Baltic sea may actually be a top-secret Nazi anti-submarine defence lost since the Second World War
- Object is raised about 10 to 13ft above seabed and curved at the sides like a mushroom
- World War II expert says object may be Nazi anti-submarine weapon
- Wire meshes could be used to baffle submarine radar and make them crash
- Area vital to German war machine
- Object has wire meshes - which could explain why dive team's equipment failed
- Divers say phones and some cameras switch off when close to the object
Sonar scans have shown that the mysterious object could be a huge Nazi anti-submarine weapon lost beneath the waves since World War II
