Undercover agents raided several internet cafes all over Northeast Ohio on Wednesday.
The state's top law enforcement agencies claimed the cafes were acting as fronts for illegal gambling and other criminal activity.
Local authorities carried out search warrants throughout the day at the locations, including at Players Club in Euclid.
350 slot machines, along with computer servers and $525,000 cash were confiscated from the locations Wednesday.
No arrests were made.
The cafes have been shut down indefinitely.
