An activist protesting in secret tunnels below Euston Station against the HS2 high-speed rail-line accused bailiffs of torture as they worked to try and remove them.
The man understood to be Lazer - real name Lachlan Blaze Sandford - is believed to be the brother of fellow tunneller Blue Sandford, 18.
Others inside the burrows are Scott Breen, 47, Larch Maxey, 48, and Swampy himself Daniel Hooper, also 48.
In a video shared from inside the burrows by HS2 Rebellion Lazer appeared to have difficulty breathing at the end of the footage.
He said: We have been down this tunnel for maybe 24, 25 hours. Since then they have kept us constantly awake via loud noises once they have been dropping dirt on us continuously so we haven’t had a chance to sleep.
