The State Law Enforcement Division and other agencies are seizing more than 700 illegal video poker machines near Swansea.
The State newspaper reports the machines were discovered early Sunday morning by Swansea police and firefighters responding to a call about leaking water and an odor of smoke at a warehouse.
SLED officials are trying to determine who owns the gaming machines, which have stickers indicating they've been used in other states including Florida, Alabama and Texas.
A Swansea magistrate declared the video poker machines illegal and if no one contests that within 15 days, the devices will be destroyed.
SLED spokesman Thom Berry says it appears the warehouse has been used as a location to both store and refurbish the gaming machines.
