Several people were hurt after the roof partially collapsed at Larry Flynt's Lucky Lady Casino in Gardena on Monday morning, authorities said.

There were a total of 11 patients, including 10 who suffered minor injuries and one who sustained moderate injuries, according to the Los Angeles County Fire Department. Seven of them were taken to the hospital, the agency added.

What caused the roof to give in was still under investigation, the Fire Department said. The property did not have any recent construction and repair work, said Brian Stevens, an inspector with department.

Crews responded to the scene at 1045 Rosecrans Ave. after receiving a call about the incident at 10:09 a.m., officials said.

Players reported hearing the walls shake and then seeing chunks of the ceiling fall two stories into the lobby.

Firefighters arrived to find the roof had collapsed on a 15-by-25-foot area in the lobby, Stevens said. Crews did not find any sign of flames.

A casino spokeswoman said the business would be closed for the rest of the day as personnel, including company architects, assessed the premises.

Officials have deemed the area safe but could not provide an estimate of when it could reopen, Stevens said.

A big portion of the roof caved in near the center of the structure, aerial footage from Sky5 shows. Ceiling panels and other parts fell on at least one cards table and the area around it, as seen in images released by Gardena police.

The casino says they’re still trying to determine what happened and would not confirm if there were previous signs of any issues with the ceiling.

"Unfortunately at this time we don't have a lot of information," spokeswoman Minda Gowen said. "We’re working with first responders, the city of Gardena and we do have our architects on site.”

The casino operates 24 hours a day, seven days a week. It's about 15,000 square feet, according to the online directory 500 Nations.
