More than 90 people were discovered inside a Houston home on Friday, police said, where investigators suspect a human smuggling operation was taking place.

COVID-19 tended to be present in some of the participants.

Several people were discovered inside the home in the 12200 block of Chessington Drive in Houston's southwest area, according to police.

Assistant Police Chief Daryn Edwards told reporters at a press conference that cops received a warning of an abduction late Thursday and worked overnight to narrow down a potential spot, leading them to the home with a search warrant on Friday.

According to Edwards, 91 people were found inside the two-story building, with five women and 86 men.

There were no children in the house, and the youngest resident appeared to be in their early twenties, according to Edwards.

Some of the people seemed to have COVID-19 and couldn't smell or taste anything, while others had fevers.
