A group of holidaymakers were forced out of Pontins after a foul-mouthed argument.
One of the members of the unruly grouped threatened to launch someone off a balcony at Pontins in Southport, a witness to the argument said.
A large police presence turned up and "had to remove" a group from their chalet, the Liverpool Echo reported.
One woman, who asked to remain anonymous, said: "I think the sun went to some people's heads this weekend.
"A lot of people's holidays were very nearly ruined by the disgusting behaviour of a few.
"They were swearing their heads off and I heard someone threaten to throw someone else off a balcony.
"Seven police cars turned up. They had to be removed from their chalet."
Merseyside Police confirmed it was contacted at 9.55pm on Sunday following reports of a disturbance.
A police spokeswoman said: "There were reports that a 19 year-old woman had been assaulted but at this stage no formal complaint has been made.
"A number of people left the site."
One guest has praised Pontins staff for how they handled the situation.
The woman said: "I genuinely don’t think the security team could have done much differently, the situation escalated so the police were called.
"They arrived promptly, the situation didn’t diffuse so the relevant parties were escorted from the site.
"I’d also certainly praise one of the security team members, Digger, who went out of his way to ensure and check all the other residents, especially children, of the block were okay."
Pontins owner Britannia has been approached for comment.
