The men blocked a road last year with plastic wrap and street signs they had pulled out of the ground, with the goal being apparently to throw chlorine bombs at the signs.

When an officer arrived to clear the roadblock a bottle of chlorine crashed down near him and released chlorine gas. He was taken to the hospital after passing out but recovered. A resident who was present also was hurt but didn't have to be taken to the hospital.

The men also set off seven other chlorine bombs in the area.
