Liverpool CEO Billy Hogan has issued a message to the club's supporters following the appalling incident that took place during the Premier League champions' trophy parade.
Hogan said: "On behalf of all of us here at Liverpool Football Club, I would like to extend our heartfelt thoughts to all those who’ve been affected by this appalling incident on Water Street yesterday evening.
"This weekend was one of celebration, emotion and joy spread across the city in our entire fan base, and it ended in unimaginable scenes of distress with this appalling incident.
"I’d like to pay tribute to our emergency services and partner agencies – Merseyside Police, North West and St John Ambulance Services, and Merseyside Fire and Rescue – who dealt with the incident, and now our hospital staff across the city who are dealing with those who are injured, including, tragically, four children.
"I would also like to thank our supporters who witnessed this event and helped each other where they could.
"We continue to work with the emergency services and the local authorities to support their ongoing investigation and once again we would ask if anyone has any further information about the incident, please contact Merseyside Police."
The Premier League released a statement yesterday evening in the aftermath of the incident in the city centre, which has left almost 50 people injured. Two people, including one child, are seriously injured, emergency services said last night.
The statement said: "Everyone at the Premier League is shocked by the appalling events in Liverpool this evening, and our heartfelt thoughts go out to all those injured and affected.
"We have been in contact with Liverpool FC and have offered our full support following this serious incident."
Former Liverpool manager Jurgen Klopp, who had returned to the city to attend the champions' final match on Sunday, said:
"My family and I are shocked and devastated. Our thoughts and prayers are with all those who are injured and affected. You'll Never Walk Alone."
Liverpool legend Sir Kenny Dalglish said: "[We are] shocked, horrified and deeply saddened about what happened at the end of the parade today.
"Our thoughts and prayers go out to everyone and their families who have been impacted by today's tragic event. Our anthem has never felt more appropriate, You'll Never Walk Alone. Your Liverpool family are behind you."
