(Indianapolis, IN) - It’s like something from The Adventures of Tom Sawyer. Members of a youth group stumbled upon a criminal’s hideout in an Indiana cave.

The discovery was reported by the Indiana Department of Natural Resources earlier this week. Members of a girls’ youth group found an abandoned campsite in a cave on the group’s property. The cave overlooks a high, rugged bluff near a river. For the sake of privacy, the location of the property was not disclosed.

According to authorities, they tracked down the squatter. The man, a convicted felon with a lengthy criminal history, was already back in jail.

The DNR reminds people that, whether you’re a criminal on the run or not, caves on private property are off-limits without permission.
