Emergency work is under way to repair the Toddbrook Reservoir dam in Derbyshire after it was damaged by heavy rain.

About 1,500 residents were evacuated from Whaley Bridge on Thursday evening amid fears they were in "mortal danger".

Engineers pumped water out of the reservoir in an attempt to stop up to 300 million gallons of water bursting through the damaged dam.

An RAF Chinook has been flying in repair materials to shore up the dam and has dropped more than 500 tonnes of aggregate.
