This kind of thing seems to be happening more often. I saw a similar article from Ontario, Canada where the perps had cut most of the way through the support beams of a wood bridge with an electric saw. We had that incident with the chain at Sunderbruch last summer. In the case with the electric saw, those people went through a lot of trouble to do potential harm to others. Why?
