Liverpool have urged supporters caught up in the chaos before Saturday's Champions League final to complete a feedback form as the club demand a formal investigation into the dangerous and frightening scenes in Paris.
The club wishes to collate as many eyewitness accounts as possible to support any inquest after fans were locked out of the Stade de France, almost crushed, attacked by gangs of thieves and teargassed by police.
Ticket holders from the final will be sent the form via email or can complete it on Liverpool's club website.
The club said: 'Liverpool FC is asking supporters who attended the Champions League final in Paris to complete a feedback form in order to support any investigation into the operational management of the event.
