Russian authorities say they will press additional charges against several Greenpeace activists being held over a protest at the country's first offshore Arctic oil rig.
Three of the 30 in Russian custody, Alex Harris, Kieron Bryan and Iain Rogers, are from Devon, and are charged with hooliganism.
It's reported some activists will now face additional charges of resisting law officers, which would carry a maximum five year prison sentence.
Russian investigators initially charged the activists with piracy.
They later changed the charge to hooliganism which has a maximum jail sentence of seven years.
David Cameron today called the charges "excessive" and urged president Vladimir Putin to make sure they can come home.
