I saw it on TV ages ago - but I found this online which is the thing I saw, I think.

"Thugs are being publicly shamed by having their names prominently displayed on a pillar in the seaside resort of Bridlington in a move which has been described as the modern-day equivalent of the stocks. The 8ft “public information” pillar, which was unveiled on the town’s Queen Street yesterday, bears the names and pictures of three young men, ranging from 14 to 22, who are all subject to anti-social behaviour orders."
