Five Extinction Rebellion protesters, including an 83-year-old, are due to appear in court today in connection with disruption to the London Underground on Thursday.
The British Transport Police (BTP) said Mark Ovland, 36, from Keinton Mandeville in Somerset, is charged with breaching his bail conditions when he allegedly disrupted a Jubilee Line train at Canning Town station in east London at around 6.45am yesterday.
Ovland is due to appear before magistrates at Highbury Corner later.
He was arrested alongside another man, a 35-year-old from Filton in South Gloucestershire, who was arrested on suspicion of obstructing the railway. The unnamed man has been released on bail.
Four others will appear at the same court charged in connection with an incident at Shadwell station, east London, on the DLR.
The BTP said they are: Margreit Bos, 32, of Chartham in Kent; Martin Newell, 52, of Sparkhill in Birmingham; Philip Kingston, 83, of Patchway in Bristol; and Sue Parfitt, 77, of Henbury in Bristol.
Two other men, aged 32 and from Lewisham and Kingston Upon Hull, were each arrested at Stratford station on suspicion of obstructing the railway, BTP said.
They have been released on bail.
Extinction Rebellion issued an apology for yesterday's protests on the Underground network, with some members concerned causing disruption to commuters had turned people away from their cause.
Commuters faced severe delays as climate change activists glued themselves to trains, as well as climbing on top of them.
In a statement, the group said they were "regretful" about the action.
