More details:
"About 100 PSG fans gathered to chase one Tel Aviv supporter, the prosecutor said, at which point Mr Granomort, who is black, tried to intervene.
"Witnesses said the crowd hurled racist insults at him, while making Nazi salutes and shouting anti-Jewish abuse at the man he was trying to protect.
"According to the French authorities, Mr Granomort was physically attacked as he shouted that he was a police officer and pulled out his gun.
"Fans interviewed on French radio said he had appeared to fire two shots in panic, as he was pushed to the ground.
"He then sought refuge in a McDonald's restaurant with the man he had been trying to defend, while police reinforcements were brought in to restore calm.
I would suppose that drinking was also involved.....
It started in a McDonalds and ended in a McDonalds?
