Officers were tipped off to the machines hidden in the rented building on Soi Batman July 16. Each machine took 10-baht coins and were in good condition, although turned off.
Police load up the confiscated slot machines to truck them away.
Building caretaker Somsak Bunklahan, 52, was found in a nearby residence, but claimed he knew nothing about the machines, which were hidden away. He was not arrested.
