Greenpeace activists arrested at Champions League final

Ten Greenpeace campaigners have been arrested at the Champions League Final in Lisbon before they were able to attach a protest banner to the stadium roof.

CNN sports correspondent Alex Thomas tweeted these pictures from the event where Real Madrid are playing Atletico Madrid.

The activists lived inside a concrete tube at Lisbon's Estadio da Luz arena for three days before the stunt against Arctic drilling energy company Gazprom.

Last year Greenpeace campaigners had to be escorted from the pitch during another protest at the 2013 Champions League Final in Switzerland.
