Residents were left fearing for their safety after shards of melting ice fell on homes and gardens from the blades of a giant wind turbine.

For about four hours people in King’s Dyke, Whittlesey, had to take cover as huge lumps – some two feet long – showered them from the 80 metre high tower on Saturday morning.
