Billy Hogan, the chief executive of Liverpool, has expressed regret to the family of a 15-year-old girl who was ”scarred for life’’ as a result of an event that occurred during a recent game at Manchester City.

In an exciting game at the Etihad earlier this month, the Reds were eliminated from the Carabao Cup, they lost 3-2 that night.

But the game was marred by a number of reported incidents off the pitch – including a projectile from part of the away section that injured a teenage City supporter in the home end below.

In a post on social media yesterday, the girl’s father said: “My 15-year-old daughter was hit by a weighted pint pot thrown from the ‘LFC section’ of fans.

“The pot ‘smashed’ on impact, she suffered a head injury and was ‘glued’ at the ground before being released later that evening. The incident occurred about 20 mins in, just after Liverpool’s first equaliser. We think it was probably thrown from block 318 as we were directly below this block.

“We are meeting officials at Manchester City this week and are asking for any information that could help us identify the thrower. The police took statements, are keen to pursue and will press charges if we can identify the culprit.”

The girl’s dad added in his message: “We have had a call from LFC directly (Billy Hogan) who apologised unreservedly on behalf of the club and I would like to stress they are as committed as we are to rooting this individual out of football and for them to face the consequences of their actions.”
