Saturday's game at the Stade de France between Liverpool and Real Madrid kicked off after a 36-minute delay; UEFA blamed "thousands of fans with fake tickets" for delays but has commissioned independent report into events in Paris; French Sports Minister also commissions report.
Liverpool CEO Billy Hogan says he has been "horrified" by accounts from fans after receiving more than 5,000 pieces of feedback about issues surrounding Saturday's Champions League final.
Liverpool set up an online form for fans to send in their own experiences from around the Stade de France, leading Hogan to condemn incidents "nobody should experience" both before and after the game.
Speaking to the club's website, Hogan thanked fans for their help with piecing together the picture of what happened outside the stadium, which saw the game delayed for nearly 40 minutes by UEFA and was originally blamed on the late arrival of fans.
"There isn't a lot of detail at this stage, it's an evolving process obviously, but we want to ensure that the appropriate steps are taken to getting the facts about what happened on Saturday in Paris," he said.
"I've spent time over the course of today reviewing some of the information and, honestly, I'm horrified by the way some men, women, children - able bodied, less able bodied - have been indiscriminately treated over the course of Saturday.
"I do think it's important to recognise we've all been rightly focused on the access issues at Stade de France; I think it's also important we don't lose sight of what happened after the match. I think we've all seen videos, photos, I've read a number of stories of absolutely horrific experiences leaving the stadium as well - crimes being committed, muggings taking place.
"Nobody should experience what our fans experienced both before or after the match. In our minds, obviously this is wholly unacceptable, which is why it's important we create this body of experiences, which clearly must be included in the independent investigation."
That investigation has not yet been commissioned by UEFA despite Liverpool's request, with Europe's governing body instead opting for an 'independent report' into the issues in Paris. This will be chaired by Portuguese MP Dr Tiago Brandao Rodrigues.
Hogan added: "This may just be a difference in language, but in our mind we requested an independent investigation rather than an independent report. So, again, detail is really important here and we'll be following up with UEFA on that over the coming days."
The Liverpool CEO also paid tribute to the groundswell of support from the media and professionals involved in the game for attempting to explain the chaotic scenes around France's national stadium, in contrast to French sports minister Amelie Oudea-Castera, who blamed Liverpool fans let "out in the wild" for the troubles.
"We want there to be a very detailed, in-depth inquiry with UEFA to see what happened, why, how and to what extent. UEFA has heard our request,we're waiting.
