The party, according to a spokeswoman for the Hollywood bar, was meant to be a mix of first responders as a way to celebrate their profession.
CNN was tipped off to the event by a source with direct knowledge of the party, who was told it would involve 100 to 150 law enforcement personnel at Sassafras Saloon.
The crowd inside was plainly visible through the bar's windows from the sidewalk Friday night, drinking cocktails under flashing lights to club music so loud that it vibrated security bars. Attendees entered through the back door, where a small desk with a candle greeted them outside.
The owners of the Sassafras Saloon rented the bar out to someone who wanted to "honor a group of first responders," according to Lisa Strangis, a spokeswoman for 1933 Group, which owns the bar on North Vine St.
While Strangis said she was unwilling to name which agency the first responders belonged to, she said the renters paid for the space and that 1933 Group employees worked the event. Strangis denied that 100 people were in the bar Friday night, but declined to provide a number. Strangis also declined to identify the party's host, saying that was private information.
"Everybody is either family or works at the same place so that's why we don't have Covid concerns," said a man who spoke to CNN outside the bar Friday night.

The man, who declined to identify himself, claimed, "Everybody's spaced there. Everybody's wearing things. Everybody's getting temperature checks."
CNN did not observe any of that occurring.
The event took place as California surpassed 500,000 cases of Covid-19 -- the highest number of cases for any US state, according to data from Johns Hopkins University. As of Sunday, more than 9,300 people in the state had died since the start of the pandemic.
In a statement to CNN on Sunday, the Los Angeles County Department of Public Health said, "We are investigating reports of a private indoor party and remind all businesses that have been ordered to close indoor operations that there are no exceptions. This is exactly the situation that puts our entire community at unnecessary risk."
But California's not alone. In recent weeks, cases have been rising in many states nationwide, with health experts and officials repeatedly pointing to large gatherings as one of several causes for the spikes in cases.
Sheriff's department denies deputies attended
Social media posts alleged that attendees of Friday's party were Los Angeles County Sheriff's Department deputies, prompting the agency to launch an investigation Saturday into whether deputies had violated county health orders.
In a statement posted on Facebook, the LASD said the event was not hosted by the department, nor were the people in social media posts LASD employees.
