He recalled that the police authorities decided to use a police bus in which tear gas sprayers are installed under the pretext of "preventing access of demonstration groups" at a time of putting down rallies and demonstrations.

This police bus has 24 long-distance tear gas sprayers installed in it but the police insists that they are "for defensive purpose, not for a preemptive attack", he charged.

He said that the Lee Myung Bak regime revealed its true colors and declared a war against the people and announced that it would intensify dictatorship.

The Lee Myung Bak regime would be well aware of the fact that it can never maintain power by dint of strength and repression, he warned.
