While 35-year-old Rocky Fisher was detained by police in Idaho, US, he wore a rather prophetic t-shirt that read: "It's all fun and games until the cops show up."

It's not known whether Fisher wore the item of clothing during a string of robberies that the authorities alleged he was involved in, alongside 19-year-old Jennifer Balfe.

Police caught the duo after receiving a tip that someone matching their description had been splashing the cash at a local casino.

KCPQ reports that the suspects allegedly robbed a bank in Cottonwood, Idaho, and are also thought to have hit two other banks in Oregon.
