A sinkhole estimated to be 35ft (9m) wide and 20ft (6m) deep has opened up in a suburban road in Hertfordshire, causing 17 houses to be evacuated.
The hole in Oatridge Gardens, Hemel Hempstead, appeared at around 07:30 GMT. Experts say recent heavy rainfall has led to an "increased number" of sinkholes.
Chief Inspector Glen Channer from Hertfordshire Police explained the ongoing situation.
