Constable Elaine Marshall at Lanark said: “It appears that the tractors have been driven from the farms, across fields, to a disused sand quarry, where they have been loaded and taken away in a larger vehicle. The entrance to this quarry is off the A73 road between Thankerton and Symington.
“I am appealing to anyone who may have been in the Thankerton or Symington area on the Friday night or early Saturday morning to call us if they saw any suspicious activity. I would also like to hear about any vehicles seen entering or leaving the old sand quarry.”
