Police seized 66 computers in Limassol on Monday in an effort to clamp down on illegal gambling.
Armed with a search warrant, officers went to search the second floor of Apollon football club at 10pm. They were initially not able to enter as the door was locked and had to break it down to gain entry.
In the building they found computers believed to have been rigged for gambling but no people. They also found notes with names and phone numbers of people believed to be customers.
It has not yet been possible to find the keys for a safe in the room.
Outside they identified 29 people – 11 men and 18 women – most of whom allegedly admitted to gambling with the computers.
Apart from the computers officers confiscated €4,950 and a disc containing data from the video surveillance system of the building.
Police said the premises were rented from Appolon and that the club has nothing to do with the illegal activities.
The 47-year-old manager was arrested and remanded for six days to facilitate investigations. More arrests have not been ruled out.
