Hi,
A friend of mine is having trouble with teenagers gathering outside a side entrance of his business premises in a partially closed laneway during the day. They are really noisy and leaving litter and even empty vodka bottles everywhere. I vaguely remember seeing a feature on RTE news a few months ago where some premises in Galway, I think, are using a sonar type gadget which emits an annoying sound that only young people can hear.
Can anyone remember this - or even better know where to source one?
AFAIK they are completely legal.
