Opportunists stealing grit from a council's roadside bins can expect to feel the full force of the law in future.
Kirklees has run out of patience with cheeky thieves who have been helping themselves to rock salt left at strategic points around the district which motorists are welcome to use to spread on the roads and pavements to help their gritters keep traffic moving.

Some have been taking the "help yourselves" message a little too literally, loading grit into sacks and taking it away.

Kirklees has already used over 12,000 tonnes of grit to combat December's Big Freeze, after stocking up in advance following lessons learned a year ago.
Cabinet member for highways, Coun David Sheard, said: "Unfortunately we are seeing more and more incidents of theft where the contents of grit bins - and sometimes the bins themselves - are being stolen.
"We have witness accounts where people turn up in a pick-up, bag the grit and steal the bin. We have also had break-ins at one of our salt storage depots.
"The whole idea of having grit bins across Kirklees is for people to use that grit on steep roads and pavements.
