On Sunday, Chinese authorities dispersed a protest by hundreds of depositors after banks failed to return their life savings.
In April, four rural banks in Henan province froze millions of dollars worth of deposits, affecting hundreds of thousands of customers.
On Sunday, more than a thousand depositors from all across China gathered in front of the People's Bank of China's Zhengzhou branch to protest.
Security officers later forcefully dispersed the crowd, according to witnesses and social media videos.
Late Sunday, police in neighbouring city Xuchang said they had detained members of a "criminal gang" who had seized control of the rural banks in 2011.
They are accused of illegally transferring funds through fictitious loans, the funds have now been seized and frozen, according to the police.
