A DUMBARTON man who exchanged $1,000 in fake US dollars for pounds has finally been locked up.

Paul Brown, of Crosslet Place, was already on his last chance from Sheriff Simon Pender when he appeared again for failing to have an immaculate community payback order (CPO) report from social workers.

The 20-year-old had previously admitted taking the counterfeit money to the Tesco in Silverburn on March 6, 2015, when he was 18.

Back at Dumbarton Sheriff Court last week, Brown's defence solicitor tried to argue he was now physically able to carry out unpaid hours of work, despite his large failure up to that point.

His solicitor insisted: "There is progress being made."

But Sheriff Pender said: "He has failed to comply with what was called for. I'm not in a position of making idle threats."

Revoking the CPO and a restriction of liberty order, he told Brown: "It was made abundantly clear that the orders made September 1 were a final chance and if the report was not exemplary, you would be facing a custodial sentence.

"It's far from exemplary."

The period in detention was limited to two months because of Brown's age, his lack of previous convictions and the small number of hours of unpaid work that he did complete.
