Eyewitnesses and content (video, photos) are needed for the police attack on Photojournalists' Union president Marios Lolos by international (and national) reporters and journos

We are looking for eyewitnesses and footage/video-pictures on the attack against the chairman of the Union of Photographers of Greece, Marios Lolos, Thursday (5 April 2012) evening in Syntagma square. By comparing the photos we concluded that there is great possibility that the incident was filmed by greek or foreign colleagues. We publish here few pictures which could help in research of people who eventually took a snapshot. If you recognize people or if you are among them, email me so I can put you in touch with Marios Lolos relatives .
People who have been circled in the photos have a great possibility to help the research.
