Investigation into the events has been made difficult due to the Chinese government's denial of it and censorship of independent and social media. Foreign journalists who attempted to investigate this incident were denied access, and later reported being unable to find unintimidated locals willing to talk to them. Internet and mobile access in the region was severely restricted for an unspecified length of time after the incident. Activists in China who provided information about it to international organizations have been arrested and sentenced for revealing "state secrets".
