HS2 protesters describe how they built tunnel, as officials warn of danger from gas and water pipes
Environmental activists have held out for their second night in the Euston tunnel, but eviction officers have said the tunnel is close to gas and water pipes and that the activists are putting their own lives at risk.
The tunnellers described how they constructed what is thought to be one of the largest tunnel networks to be occupied by protesters in one of the busiest parts of London without being detected.
