Blac Chyna Was Partying, Being 'Obnoxious' on Hawaii Vacation Before Police Were Called: Source

Before authorities responded to Blac Chyna‘s suite at the Ritz-Carlton Residences in Honolulu, Hawaii, on Monday, she had already made quite a splash at the luxury hotel.

A source told PEOPLE that Chyna, 30, spent Sunday with a group of friends.

“They hung out by the pool, partied and were loud,” the source said. “They are not the typical hotel guests.”

“They were definitely being inappropriate in several ways,” continued the source. “The girls were showing nipples, they were twerking and just being obnoxious. Hotel management had complaints, because there were families with kids that didn’t like the way they behaved.”

Officers and paramedics responded to the suite after a fight broke out between Chyna and the rapper she’s been dating, Kid Buu, 30.

“Someone from their group called 911,” the source said. “Hotel security escorted police officers and paramedics to a suite, where Blac Chyna was with a group of people.”

“It was more of a ‘he said, she said’ situation. They both had complaints to the police, but in the end no one was arrested or taken to the hospital,” continued the source, adding that Chyna and Kid Buu “were both intoxicated.”

“Again, this is not a typical incident at the hotel,” the source said. “In fact, this behavior is 100 percent unacceptable.”

A rep for Chyna, who shares 2-year-old daughter Dream with her ex Rob Kardashian, did not respond to PEOPLE’s request for comment.

The Honolulu Police Department confirmed that the incident is currently under investigation.

“Shortly before 9 a.m. today, a female visitor staying in Waikiki reported being assaulted by a male acquaintance. The victim reported that she and the suspect had been involved in an argument several hours earlier, and the argument had escalated to a physical confrontation,” a media liaison officer said in a statement to PEOPLE. “The male left the area after the confrontation and has not been located.”

“This incident has been classified as abuse of a household member,” the statement continued. “The investigation is continuing, and no further information is being released at this time.”

In a statement to PEOPLE, the Ritz-Carlton Residences’ director of public relations said, “As a matter of privacy, we are unable to comment.”
