Police, cycling groups and bikers are condemning those responsible for stretching a wire across a narrow road in Dumfries and Galloway.
The fishing line was strung at throat height across the quiet C125n backroad between Sanquhar and Kelloholm, near Drumbuie. It was found by a passerby at 5am on July 26.
Officers accept it may have been youngsters misguidedly thinking it was a 'practical joke'. However, they say it is being treated as a serious crime as the level of danger to the public was was so severe.
PC Stephen Aulb, from Dumfries and Galloway Police said:
Motorcyclists have also highlighted the danger caused by this sort of act. Nigel MacDonald said the wire could have caused a tragedy had someone collided with it. He said:
Anyone who may have seen suspicious activity in the area prior to July 26 is asked to contact Dumfries and Galloway Police on 101.
