The group placed the effigy on top of the bonfire. As the flames consumed it, people in the group chanted "help me, help me." In the video they laughed and cheered, underscoring that this was an attempt at black humor rather than a considerate act of protest.

Soon after the video was posted, the police launched an investigation into it.
