Robert Wiseman Dairies has teamed up with Crimestoppers to distribute millions of special edition milk cartons throughout Scotland to promote the latest campaign from the crime-busting charity.

Callers to the freephone number printed on the cartons can remain anonymous and give information on crimes without fear of the call being traced or of having to attend court as a witness.

The new campaign, featuring a schoolboy called Ben and ITV Popstars contestant Darius Danesh, encourages younger callers by offering the chance to win mobile phone top-up vouchers.

Wiseman sales and marketing director Sandy Wilkie said: “The milk carton is a powerful tool.”
