Jurgen Klopp reportedly scared bystanders by 'screaming and shouting' following the club's FA Cup defeat to Manchester United on Sunday.
The Reds scored three times courtesy of goals from Alexis Mac Allister, Mohamed Salah and Harvey Elliot.
Yet United ended up winning the dramatic contest at Old Trafford 4-3 after efforts from Scott McTominay, Antony, Marcus Rashford and Amad Diallo.
After the game, Klopp stormed out of an interview with Norwegian TV channel ViaPlay.

The 56-year-old said a reporter had asked him a 'dumb question' and was clearly livid at the line of questioning, with fans since turning on the iconic boss on social media.
"You are obviously not in a great shape and I have no nerves for you," he said as he exited the media zone.
When asked if his side lacked energy in extra time, he added: "That's a bit of a dumb question.
"If you see us often, you can ask us the other times why we have so much energy.
"I don't know how many games we've had recently and how many Manchester United have had. That's sport.
"I'm really disappointed about that question, but you thought obviously it's good.'
Now, reporter Niels Christian Fredericksen has shed new light on the matter - saying Klopp was 'shouting and screaming' in his direction.
"I was very surprised by it," he told Danish outlet Tipsbladet.
"And the people standing around were scared, and they were almost pressed up against the wall like: 'Wow, what the hell just happened here?'
"It continued after what you saw on the TV.
"He continued down the corridor, shouting and screaming at me.
"I went after him too, because I thought it was a strange thing."
He continued: "I was very surprised, while some people looked very shocked, and they asked: 'Are you OK?' and damn it, I'm OK."
Given Klopp claimed the reporter was 'not in great shape', some have wondered if the Liverpool boss had made a personal remark.
Fredericksen doesn't see it that way, however, and insists the outgoing Reds boss wasn't being rude and crossing a line.

"No, no, no, no, that's not what he meant at all," he added.
"Firstly, I'm not overweight, and if I was, he would never, ever say that. Klopp is not like that.
"It wasn't meant like that at all. He's not obnoxious at all.
"He thought I was incapable and unfit to ask questions. There was none of that other stuff."
Though Klopp was enraged, it was a significant victory for United boss Erik ten Hag.

And the Dutchman was delighted after the win, with his side now hoping to make the FA Cup final for the second year in a row.
“It was, of course, fantastic and the team showed the resilience and determination, to win this game," he said.
"And we have had so many setbacks, so I’m really proud of the team. Not only in this game, but the whole season, we have so many setbacks, and they can deal with it.
"They are very strong, mentally, and it helps, of course, that the fans go behind us. But we energised the fans, they got behind us.”
