On October 25, a group of people silently filmed the Assembly proceedings, the first to be arrested was Thi Le. As she was being removed from the gallery officer Mael approached to "assist" with the arrest. Mael has a history of being inappropriately forceful and grabby with female protesters, so Damon was planning on following them out to keep an eye on them as they arrested Thi.
Damon was stopped on his way up the stairs and told he couldn't go out that way, he was directed to leave out of the other side of the gallery, and as he follows the direction of the police to leave through the other door he is arrested.
This was months ago, Damon has requested copies of the police report to see what he is being accused of doing and they either lost the report or never wrote one, as he has yet to receive the document. He has COURT coming up soon for this charge and still doesn't know what he was arrested for.
