Police are hailing a four-day operation against prostitution in Nottingham as a success.
A total of 32 men were caught trying to buy sex from an undercover officer in the Mapperley and Arboretum areas.
Some will now attend a special course. This year 47 men have attended the Change Programme and so far none has reoffended.
Insp Andy Rooke said the so-called "test purchase" operations would continue in the future.
He said: "We use it on a regular basis. We've used it in the past and we'll continue to use it.
"It does help us to tackle some of the kerb crawling issues, but we also use high-visibility patrols.
"We have technology that we use as well to try to identify people that are in the area that shouldn't be."
