When mystery Bristol street artist Banksy rocked up in the bombed out towns of Ukraine last year, he left artwork on the ruined buildings that lifted the nation.
And now, it seems, the Ukrainian authorities are so enamoured with the works Banksy left behind, that they are going to extraordinary and high-tech lengths to protect them.
The police and military personnel obviously have better things to do than guard some street art, so the authorities in the Kyiv region have installed some of the latest technology to protect the works of art from the threat of being stolen by art thieves or vandalised.
