Crime in Development
Occasionally a badger sett is damaged or destroyed during development works. This may occur whether the developer is aware there is a sett there or not. In both instances it must be dealt with by the police.
Destruction of or blockage of the entrances to a badger sett may well mean the death of badgers within it and should always be investigated thoroughly.
If you suspect that this has occurred contact the police and your local group as soon as possible.
