THE METROPOLITAN Police has set up a special unit to protect badgers from house builders.
The Met's wildlife liaison officer, Andy Fisher, said police were keen to work with the construction industry to protect the endangered animals.
And he warned contractors they face stiff fines if they disturb badger setts.
Mr Fisher said: 'Most builders and developers uphold the law and work closely with English Nature to prevent sett disturbance.'
The maximum fine for interfering with badger setts is £5,000 or a six- month prison sentence.
Badger setts are most likely to be disturbed during the winter months when the animals spend a lot of time underground with their litters.
