On October 16, British pop star Liam Payne, formerly of the boy band One Direction, died when he fell from a third-story balcony of a hotel he was staying at in Buenos Aires, Argentina.

The Public Prosecutor's Office in the South American nation has now arrested and charged three individuals in connection with Payne's death, including one person who was described as having "accompanied the artist on a daily basis" during his time in Argentina, Sky News reported.

That individual has been criminally charged with "abandonment of a person followed by death," along with a charge for supplying illegal narcotics to Payne, which has also been pressed against an employee of the hotel and an alleged drug dealer.

Arrests made and charges pressed over Payne's death

The arrests and charges in connection with Payne's death were announced in a press release from the prosecutor's office that outlined the status of the investigation thus far that has been led by prosecutor Andrés Esteban Madrea.

That investigation has involved "several dozen testimonies" from witnesses, family and friends, hotel staff, and experts, as well as the review of more than 800 hours of surveillance camera footage from the hotel and the surrounding area, plus a "forensic extraction" of data from Payne's cellphone and others, a check of the hotel's records, search warrants executed on nine residences in the city, and an autopsy and toxicological tests of Payne's body.

Following all of that, the prosecutor determined that the three charged individuals had all provided Payne with illicit drugs on multiple occasions in his final days, and the toxicology report revealed that he had "trace amounts" of alcohol, cocaine, and an undisclosed "prescription antidepressant" in his system.

Investigators also determined that Payne likely didn't commit suicide, nor was he pushed off the balcony. Rather, based on the absence of any defensive moves or reflexes to protect himself, it is believed that Payne was in "a state of semi or total unconsciousness" when he fell from the balcony of his third-floor room at the hotel.

Initial reports of fatal incident align with details in prosecutor's report

According to Fox News, the details from the prosecutor's report seem to align with what was known from initial reports about the incident, including an emergency call from a hotel employee for help with a guest who was "under the influence of drugs and alcohol who had destroyed some objects in the room."

Indeed, police had described Payne's hotel room as being "in complete disarray" with "various items broken," and there was ample evidence strewn about of alcohol and drug abuse, including cocaine and a common antidepressant known as clonazepam or Klonopin, among other drugs.

The report also revealed that, roughly two weeks after his death, Payne's body had finally been delivered to the custody of his father, Geoff Payne, "last weekend."

Friend who was possibly charged speaks out

While the Argentinian prosecutor's office did not name the arrested and charged suspects, the New York Post's Page Six reported that a friend of Payne, Argentinian businessman Rogelio "Roger" Nores, may have identified himself by issuing a statement that professed his innocence of any wrongdoing in the fatal incident.

"I never abandoned Liam. I went to his hotel three times that day and left 40 minutes before this happened," Nores said on Thursday. "There were over 15 people at the hotel lobby chatting and joking with him when I left."

He insisted that he "could have never imagined something like this would happen" and that he gave a "statement to the prosecutor on Oct. 17 as a witness" but hasn't "spoken to any police officer or prosecutor ever since." He also was adamant that he "wasn’t Liam’s manager" -- the prosecutor said the charged friend repeatedly identified himself to others as Payne's manager -- but was just a "very dear friend" who was still mourning the loss.

Nores added that he was "really heartbroken with this tragedy" and pointed out that he'd sent an email to Payne and others in August to raise his "concerns" about the "well-being" of his friend. If Nores is the first charged individual, and if he is convicted, he could face up to 5 to 15 years in prison.
