Meanwhile, the original anti-junky lights have been found to not only not work (ask any junky with a felt-tipped pen), but to also have unintended consequences:
Public toilets in Church Street, in Rugby town centre, were closed in February after a shocked cleaner discovered two people having sex inside. In a report to officers, Rugby borough council head of engineering and works David Johnson said the toilets were still suffering anti-social behaviour.
“The subdued lighting encourages an atmosphere conducive to sexual activity, while it is off-putting to the public wishing to use the facilities.
“Another problem is that graffiti written in certain pens looks spectacular under UV lighting.”
