Three people who tunnelled underground outside Euston station to protest against HS2 redevelopment, including veteran campaigner Daniel Hooper, known as Swampy, have been granted bail.

Hooper, 47, Isla Sandford, 18 and Juliett Stephenson-Clarke, 22, all appeared at Westminster Magistrates Court on Friday charged with obstructing or disrupting a person engaged in a lawful activity.

The three, who had occupied the tunnel system under Euston Square Gardens in central London, were arrested after they returned to the surface on Thursday.
