To customers in the eastern city of Nanjing the interior looked like any other state-owned bank, with uniformed clerks working behind the counters, the Southern Metropolis Daily website reports . Almost 200 people deposited their cash, including a businessman who handed over 12m yuan ($1.9m; £1.3m) in 2014. But he grew suspicious when he wasn't paid the promised interest on his money, and went to the police after the bank refused to return his savings. A police investigation found that it was actually a rural cooperative, which had none of the accreditations required to operate as a bank. It had been promising interest rates of 2% per week and high interest subsidies, police say.
