(Lawrenceburg, Ind.) - Folks heading home from southeast Indiana casinos are being warned to watch their backs.

A man in Colerain Township-Hamilton County was robbed at gunpoint in his own garage early Monday morning after he had just arrived home from one of the local riverboats.

Police say there have been more than a dozen other similar incidents in recent weeks.
