Mountain bikers are being warned to be extra vigilant after a number of traps have been found near Dove Stone Reservoir at Greenfield.
Some of these are near to the plantation at Chew and the reservoir itself. Wires have been tied between trees and obstacles and unsafe rocks placed in the landing areas of jumps.
These traps can cause serious and even lethal injuries. Any information about these deliberate acts should be passed to the police as soon as possible.
