Twenty-four-hour sports gyms, or fitness clubs that are open late at night and in the early morning, are increasing in number.
California Fitness has shut down its Singapore locations, meaning only one branch of the troubled gym chain remains open.
Two staff members at California Fitness were arrested by customs officers on Wednesday afternoon over an allegation that a customer was offered a free trial before being tricked into making a HK$140,000 credit card payment for private training classes without her consent.
