However, in September 2010, it was reported that Beijing Municipal Public Security Bureau officials have detained Zhang Jun, chairman of "Anyuanding Security Service Company", and Zhang Jie, general manager of this company, for "illegally detaining people and illegal business operation". The company started business in 2004. In 2008, it began to help Beijing liaison offices of local governments to stop petitioners from their regions from petitioning in Beijing. The company employees first lied to the petitioners, telling them that their lodging has been provided. Then, the company employees took them to abandoned hotels or rented houses in suburban Beijing, seized their IDs and phones, and locked them up until the liaison offices told the company to help send the petitioners back to their hometowns. Later, the company expanded its business and got more clients including even remote village governments to help the local governments "maintain stability".
