Kerb crawler, 95, given warning A 95-year-old man has been arrested during a crackdown on kerb-crawlers. Police detained the pensioner after he picked up a prostitute in Bournemouth, Dorset, but he was let off with a warning because of his age. Insp Mark Kelly said: "He picked up a girl, took her somewhere nearby and officers intervened as they were getting down to sexual activity." During the six-month crackdown, police arrested 40 men in the town and 35 will be attending a rehabilitation course. Insp Kelly added: "They arrested him and brought him in but the custody sergeant felt a reprimand would be most suitable rather than put him through the courts system. "We felt with his age it was not in the public's interest to proceed any further." Since April, 26 prostitutes have been arrested in the town. Police said that if a man was found kerb-crawling a letter could be sent to the licence holder of the vehicle, which could turn out to be his wife or employer.

Disregarding the aspect of whether or not criminalizing prostitution is stupid, of more immediate concern is what kind of offense that *would* result in the prosecution of the guy. Moreover, what's the illegal maximum age for visiting a prostitute?
