She was Ukraine’s ‘Joan of Arc.’ Now she’s accused of plotting a coup in Kiev.

KIEV, Ukraine — Two years ago, Nadiya Savchenko, a Ukrainian helicopter pilot who had been taken prisoner by pro-Russian forces in the country’s east, returned from captivity to a tumultuous hero’s welcome.

Today she is once again behind bars — only this time she has been put there by Ukrainian authorities.

Savchenko was arrested last week on charges of plotting a violent coup d’etat, which was allegedly supposed to include the murder of President Petro Poroshenko and other top officials.
