Zak Kostopoulos, a Greek LGBTI activist and drag performer, died Friday after a brutal attack in an Athens shopping district. According to NBC News, two men have been arrested in connection with Kostopoulos’ death but details remain unclear. Video of the incident surfaced on social media, though police have yet to confirm its authenticity. In the grainy video, a person who could be Kostopoulos is seen attempting to escape a locked jewelry store, first by smashing its glass door with a fire extinguisher, then by crawling through a broken window. As he makes his way out of the store, two men repeatedly kick him in the head as a mob looks on.
