The SIIO spokesman also said with regard to a number of rumors having appeared on weibo.com and t.qq.com, the two popular microblogging sites have been "criticized and punished accordingly" by Internet information administration authorities in Beijing and Guangdong respectively.
The spokesman did not elaborate what the punishment was, but said the two websites had pledged to "strengthen the management."
Beijing police in a statement Friday urged Internet users to abide by laws and be vigilant against online rumors, which severely disturb the public order, undermine social stability and deserve punishment.
An editorial to be carried in the Saturday edition of People's Daily, the flagship newspaper of the Communist Party of China, said anyone involved in creating and spreading rumors will surely be punished according to laws.
"By falsely packaging lies and speculation as 'truth' and 'existence,' online rumors undermine the morale of the public, and if out of control, they will seriously disturb the public order and affect social stability," reads the article.
