Police are calling for information after staff discovered a cannabis plot at the Buckler Burn River Flats near Glenorchy.

Officers recovered six plants in the area near the gravel pit at the entrance to Glenorchy and there was evidence that other plants grown there had been harvested.

Police are most concerned about the use of booby traps surrounding the plot, including planks of wood with large nails sticking up.

The traps were hidden in long grass and someone could have easily stood on them causing serious injury.
