HM Coastguard Lowestoft urged caution for anyone visiting the beach, particularly those with pets after the metal rod appeared on the shore.

The rod is from large concrete walls which have since fallen onto the beach.

In a plea on Facebook, a spokesperson said: 'During a walk along Pakefield and Kessingland Beach, we discovered considerable cliff erosion caused by the winter weather.

'This happens every year and we lose some sections at an alarming rate.

'Be aware that old wartime pill boxes and large concrete walls often fall onto the beach, as well as trees and shrubs. Inside these slabs of concrete are metal rods used to strengthen the walls. These can become a hazard.

'Extreme caution should be used when walking on the beach. Be extra vigilant with your pets as they bound into the sea. There are often spikes that become visible.

'Be safe, be aware, keep your children and dogs close and enjoy our beautiful beaches.'
